Gadgetwise Blog: Q&A: Creating Customized Shortcuts for Microsoft Word

I find the keyboard shortcut for adding a comment to a Word document cumbersome. Can I change it to different keys?

Microsoft Word’s keyboard shortcut for inserting an editorial comment into a document under review (Control-Alt-M in the Windows version or Command-Option-A for the Mac edition) does take three keys to execute, but you can reassign the command to fewer (or a more comfortable combination of) keys.

In recent versions of Word for Windows, click the File tab, then Options and then select the Customize Ribbon tab. In the “Customize the Ribbon and keyboard shortcuts” area, click Customize. Choose the name of the template or document name you want to use in the “Save changes in” area of box.

In the list of Categories shown, select the menu name or category that contains the command you want to change, like “Insert.” In the Commands list, choose the name of the particular action you want to use, like “InsertNewComment.” The box shows the current keys that are assigned for the shortcut, provides a field to create a custom key combination and a button to assign it. Click OK when you have assigned the keys you want to use for the Insert New Comment command; your new command will replace any combinations already in use as shortcuts.

Microsoft has detailed instructions for making custom keyboard shortcuts for Windows on its site, as well as the equivalent steps for Mac users who want to make their own keyboard shortcuts. The box for creating custom keyboard shortcuts also includes a reset button so you can revert to Microsoft’s original shortcuts for the program’s commands if you choose.

Well: Ask Well: Swimming to Ease Back Pain

Many people find that recreational swimming helps ease back pain, and there is research to back that up. But some strokes may be better than others.

An advantage to exercising in a pool is that the buoyancy of the water takes stress off the joints. At the same time, swimming and other aquatic exercises can strengthen back and core muscles.

That said, it does not mean that everyone with a case of back pain should jump in a pool, said Dr. Scott A. Rodeo, a team physician for U.S.A. Olympic Swimming at the last three Olympic Games. Back pain can have a number of potential causes, some that require more caution than others. So the first thing to do is to get a careful evaluation and diagnosis. A doctor might recommend working with a physical therapist and starting off with standing exercises in the pool that involve bands and balls to strengthen the core and lower back muscles.

If you are cleared to swim, and just starting for the first time, pay close attention to your technique. Work with a coach or trainer if necessary. It may also be a good idea to start with the breaststroke, because the butterfly and freestyle strokes involve more trunk rotation. The backstroke is another good option, said Dr. Rodeo, who is co-chief of the sports medicine and shoulder service at the Hospital for Special Surgery in New York.

“With all the other strokes, you have the potential for some spine hyperextension,” Dr. Rodeo said. “With the backstroke, being on your back, you don’t have as much hyperextension.”

Like any activity, begin gradually, swimming perhaps twice a week at first and then progressing slowly over four to six weeks, he said. In one study, Japanese researchers looked at 35 people with low back pain who were enrolled in an aquatic exercise program, which included swimming and walking in a pool. Almost all of the patients showed improvements after six months, but the researchers found that those who participated at least twice weekly showed more significant improvements than those who went only once a week. “The improvement in physical score was independent of the initial ability in swimming,” they wrote.

DealBook: Blackstone Keeps Most of Its Money With SAC

9:06 p.m. | Updated

The Blackstone Group, the largest outside investor in the hedge fund SAC Capital Advisors, said it would keep most of its $550 million with the hedge fund for three more months while it monitors developments in the government’s insider trading investigation.

Blackstone acted as SAC’s clients faced a regularly scheduled quarterly deadline on Thursday to decide whether to continue investing with the hedge fund giant run by Steven A. Cohen.

Despite posting one of the best investment records on Wall Street — returning 30 percent annually over the last two decades — SAC has been fighting to keep investors’ money as an investigation into criminal conduct at the fund has intensified. Since November, when prosecutors brought the most recent SAC-related case, against Mathew Martoma, a former SAC employee, clients have been weighing whether to continue their relationship with the fund. Mr. Martoma has denied the charges.

Large hedge fund investors like Blackstone rarely make public pronouncements about their intentions, but given the heightened interest in SAC, the investment firm issued a statement explaining the rationale for its decision.

Blackstone said the money it withdrew was in the normal course of business and was unrelated to any of SAC’s problems. Blackstone, which runs the world’s largest so-called fund of funds, placing nearly $50 billion with outside managers, is seen as a bellwether in the hedge fund industry.

“While we submitted redemptions for certain accounts as appropriate, BAAM successfully preserved flexibility for our clients by extending our decision timeline,” Peter Rose, a Blackstone spokesman, said in a statement, referring to Blackstone Alternative Asset Management, the segment that invests with hedge funds. “We will use this period of time to evaluate all additional information which becomes available.”

It was unclear how much money SAC’s clients redeemed Thursday. The fund, which is based in Stamford, Conn., had warned its employees that it expected it could face at least $1 billion of withdrawals. A Citigroup unit that manages money for wealthy families has disclosed that it was withdrawing its $187 million investment.

While several other former SAC employees have previously been charged with insider trading crimes, the Martoma prosecution has changed clients’ calculus because the trades at the center of the case involve Mr. Cohen. In addition, the Securities and Exchange Commission warned SAC that it might file a civil fraud lawsuit against the fund related to the trades. Mr. Cohen has not been charged and has said that he has acted appropriately at all times.

Federal prosecutors are also nearing a decision on whether to bring criminal charges against Michael Steinberg, a longtime SAC portfolio manager, related to trading in Dell and Nvidia stocks. A lawyer for Mr. Steinberg, Barry Berke, said in a statement that his client did nothing wrong.

Unlike other hedge funds that can be forced to shut down after a wave of client withdrawals, SAC is in an unusual situation. Only about 40 percent of the $14 billion managed by SAC, or about $6 billion, comes from outside clients. The rest belongs to Mr. Cohen and his well-paid staff.

In addition, SAC has policies that limit the amount of money a client may withdraw in any one quarter. Clients may withdraw only 25 percent of their investment every three months. That means if a client put in a so-called redemption request on Thursday, it would receive its money back in quarterly installments beginning March 31, and would get its last dollar out on Dec. 31.

Blackstone negotiated a way to buy itself time without delaying its ability to withdraw its investment from the fund. SAC agreed to a new redemption policy that it will extend to other clients, allowing them to keep their money with SAC for another quarter. After that, if clients decide to end their relationship with SAC, the fund will return their money in three installments.

Under the new policy, SAC is letting clients take a wait-and-see approach, monitoring the investigation for developments that could damage the fund. If they withdraw, they will still have all of their money returned by year-end.

SAC’s recent investment results have been solid, but have lagged the Standard & Poor’s 500-stock index. The fund returned about 13 percent in 2012 and 2.5 percent last month.

IHT Rendezvous: Glimpses of Jean Arp's World

CLAMART, France—The street is typical French suburbia, gray and peaceful, a far stretch from the narrow sidewalks, rooftops and, in early 20th century, artists’ studios of Montmartre, but only a few kilometers from Paris. Yet, in the 1930s, up this steep and curvy stretch, lived two members of the avant-garde — Jean Arp and Sophie Taueber. Joan Miro, Max Ernst, Marcel Duchamp and James Joyce were among their visitors.

Arp (1886-1966) was a pioneer of surrealism and a member of the Dada movement, the branch of surrealism that called for a return to childhood spirit and the destruction of all established rules. After working in Zurich and then in Paris in Montmartre, he and Taueber, another free thinker (they eventually married), bought a piece of land in Clamart and built a house at the edge of a forest. Taueber designed it, influenced by the Bauhaus, Le Corbusier and Charlotte Perriand.

More than 80 years later, the three-story “maison-atelier” still stands, and a decade-long renovation has just been completed.

“It’s a house imbued with the serenity and simplicity of both artists,” said Claude Weil-Seigeot, the president of the Arp Foundation in France. “When I saw all of this might disappear if no one acted, I decided to give battle,” she said.

Keeping the building “modest and intimate” was a prerequisite for Ms. Weil-Seigeot when work began on the house in 2003. The renovations, including the construction of a little bookstore that opens onto the garden, were all done using the typical “meulière” stone of the Paris suburbs that Taueber had used in the ’30s. Ten years later, the work, done little by little so the house would not have to close to visitors, is finally finished, simultaneously with the publication of “Atelier Jean Arp et Sophie Taueber,” an art book, with text by Renaud Ego, on the history of the house and its occupants.

There are three Arp foundations in Europe: The one in Clamart, which preserves the atelier where Arp lived and worked for most of his life; one in Locarno, Switzerland, founded by Arp’s second wife, Marguerite Arp-Hagenbach, and the Stiftung Arp eV, a German organization, which holds the rights of reproduction of Arp’s work and owns most of the artist’s sculptures.

Relationships among the three foundations were problematic in the past, according to the German foundation’s curator, Maike Steinkamp.

“Now the aim is that we cooperate; when there are problems with authenticity, we talk,” she said. A publication released last year, “Hans Arp. Sculptures— A Critical Survey,” by Kai Fischer and Arie Hartog, took note of all known sculptural objects related to Arp including posthumous and unauthorized casts, causing some controversy with its revelations.

Its aim was to create transparency in Arp’s work, said Ms. Steinkamp. “We are happy with that objective and will now not be casting any new sculptures because of all the problems the survey revealed about the past.”

The German and French foundations wrangled over some of Arp’s work; some of it had been moved to Germany. Once it had been established that it was Arp’s wish that they remain in his atelier, they were returned. Most of the sculptures are now back on view in Clamart. “When I’m asked who picked the sculptures to be on show here, I like to joke and say ‘it was all work of the bailiff.’” Ms. Weil-Seigeot said, smiling. “It’s the bailiff’s collection.”

Only about 2,000 visitors tour the house each year, she said, by necessity. “It’s so intimate, when there are more than 30 people in the house at once, it’s panic!”

Through the windows, up the stairs, you can peer into the artists’ workspace. There you see drawings, collages, words and sculptures. Even in deep winter, Arp’s sculptures reflect the garden’s afternoon light.

“He was very attached to the dialogue between nature and his art,” Ms. Weil-Seigeot said.

Trees tower above the studio with only natural light filtering in. In his definition of Dada, Arp introduces nature:

“Dada is direct like nature and tries to give essential room to every thing. Dada is for infinite meaning and definite media,” he wrote.

His sculptures have the shapes of curvaceous bodies, old sinuous trees or seashells that stayed underwater so long that their surfaces have eroded.

“We try to let visitors approach the artwork freely, we don’t want to impose any cultural filter on them,” Ms. Weil-Seigeot explains, following the artist’s desire to let art speak to the senses.

“One has to create like nature,” Arp once said.

When schoolchildren come for group visits, they are given gloves and are allowed to touch the sculptures in the garden to feel their smooth surface. No words are needed.

“They are the ones who understand it the best,” says Ms. Weil-Seigeot. “Because they have no filter yet.”

The Fondation Arp is at 21 rue des Chataigniers in Clamart. Visiting hours are Friday, Saturday and Sunday from 2 p.m. to 6 p.m. by appointment. More information at www.fondationarp.org

Well: Life, Interrupted: Crazy, Unsexy Cancer Tips

Life, Interrupted

Suleika Jaouad writes about her experiences as a young adult with cancer.

Every few weeks I host a “girls’ night” at my apartment in Lower Manhattan with a group of friends who are at various stages in their cancer treatments. Everyone brings something to eat and drink, and we sit around my living room talking to one another about subjects both heavy and light, ranging from post-chemo hair styling tips, fears of relapse or funny anecdotes about a recent hospital visit. But one topic that doesn’t come up as often as you might think — particularly at a gathering of women in their early 20s and 30s — is sex.

Actually, I almost didn’t write this column. Time and again, I’ve sat down to write about sex and cancer, but each time I’ve deleted the draft and moved on to a different topic. Writing about cancer is always a challenge for me because it hits so close to home. And this topic felt even more difficult. After my diagnosis at age 22 with leukemia, the second piece of news I learned was that I would likely be infertile as a result of chemotherapy. It was a one-two punch that was my first indication that issues of cancer and sexual health are inextricably tied.

But to my surprise, sex is not at the center of the conversation in the oncology unit — far from it. No one has ever broached the topic of sex and cancer during my diagnosis and treatment. Not doctors, not nurses. On the rare occasions I initiated the conversation myself, talking about sex and cancer felt like a shameful secret. I felt embarrassed about the changes taking place in my body after chemotherapy treatment began — changes that for me included hot flashes, infertility and early menopause. Today, at age 24, when my peers are dating, marrying and having children of their own, my cancer treatments are causing internal and external changes in my body that leave me feeling confused, vulnerable, frustrated — and verifiably unsexy.

When sex has come up in conversations with my cancer friends, it’s hardly the free-flowing, liberating conversation you see on television shows like HBO’s “Girls” or “Sex and the City.” When my group of cancer friends talks about sex — maybe it’s an exaggeration to call it the blind leading the blind — but we’re just a group of young women who have received little to no information about the sexual side effects of our disease.

One friend worried that sex had become painful as a result of pelvic radiation treatment. Another described difficulty reaching orgasm and wondered if it was a side effect of chemotherapy. And yet another talked about her oncologist’s visible discomfort when she asked him about safe birth control methods. “I felt like I was having a conversation with my uncle or something,” she told me. As a result, she turned to Google to find out if she could take a morning-after pill. “I felt uncomfortable with him and had nowhere to turn,” she said.

This is where our conversations always run into a wall. Emotional support — we can do that for one another. But we are at a loss when it comes to answering crucial medical questions about sexual health and cancer. Who can we talk to? Are these common side effects? And what treatments or remedies exist, if any, for the sexual side effects associated with cancer?

If mine and my girlfriends’ experiences are indicative of a trend, then the way women with cancer are being educated about their sexual health is not by their health care providers but on their own. I was lucky enough to meet a counselor who specializes in the sexual health of cancer patients at a conference for young adult cancer patients. Sage Bolte, a counselor who works for INOVA Life With Cancer, a Virginia-based nonprofit organization that provides free resources for cancer patients, was the one to finally explain to me that many of the sexual side effects of cancer are both normal and treatable.

“Part of the reason you feel shame and embarrassment about this is because no one out there is saying this is normal. But it is,” Dr. Bolte told me. “Shame on us as health care providers that we have not created an environment that is conducive to talking about sexual health.”

Dr. Bolte said part of the problem is that doctors are so focused on saving a cancer patient’s life that they forget to discuss issues of sexual health. “My sense is that it’s not about physicians or health care providers not caring about your sexual health or thinking that it’s unimportant, but that cancer is the emergency, and everything else seems to fall by the wayside,” she said.

She said that one young woman she was working with had significant graft-versus-host disease, a potential side effect of stem cell transplantation that made her skin painfully sensitive to touch. Her partner would try to hold her hand or touch her stomach, and she would push him away or jump at his touch. It only took two times for him to get the message that “she didn’t want to be touched,” Dr. Bolte said. Unfortunately, by the time they showed up at Dr. Bolte’s office and the young woman’s condition had improved, she thought her boyfriend was no longer attracted to her. Her boyfriend, on the other hand, was afraid to touch her out of fear of causing pain or making an unwanted pass. All that was needed to help them reconnect was a little communication.

Dr. Bolte also referred me to resources like the American Association of Sexuality Educators, Counselors and Therapists; the Society for Sex Therapy and Research; and the Association of Oncology Social Workers, all professional organizations that can help connect cancer patients to professionals trained in working with sexual health issues and the emotional and physical concerns related to a cancer diagnosis.

I know that my girlfriends and I are not the only women out there who are wondering how to help themselves and their friends answer difficult questions about sex and cancer. Sex can be a squeamish subject even when cancer isn’t part of the picture, so the combination of sex and cancer together can feel impossible to talk about. But women like me and my friends shouldn’t have to suffer in silence.

Letter from India: Executions as a Matter of Opinion







NEW DELHI — When Indian cops take defendants to court, they walk holding hands, as if they were grim lovers. In photographs and video footage of Muhammad Afzal, also known as Afzal Guru, he can be seen being led in this manner by a man in uniform. But the state had no affection for Mr. Afzal.




He was found guilty of helping terrorists who attacked the Indian Parliament in 2001, and thus of “waging war against India,” among other serious charges. His was a long and complicated case, with gaping holes in the police investigation; even the Supreme Court, the highest in India, found that he was implicated not by direct evidence, but by a clutch of circumstances that pointed to his involvement.


Though the courts found Mr. Afzal to be complicit in the attack on Parliament, it remains unclear just how significant his role in the plot was.


Last Saturday morning, he was hanged in secrecy in the Tihar jail in New Delhi. According to the newspaper The Hindu, the 43-year-old was informed of his fate on the morning of the hanging, and after regaining his composure he wrote a letter to his wife and son, which he handed to a jail official as he emerged from his cell for the short walk to the gallows.


The hanging of Mr. Afzal, which surprised the nation and shocked his family, led to expressions of joy from politicians of various parties, as well as ordinary citizens. The world that Mr. Afzal was found unfit to live in was also a world that had the capacity to celebrate a human death. But there were also many who were disgusted, and who protested — and not merely in the Kashmir Valley, Mr. Afzal’s birthplace, where a curfew was imposed — because the execution has raised a number of deep concerns. Taken together, they point to a disturbing question: Is the Indian justice system competent, consistent and fair enough to grant the state the moral authority to terminate a human life?


On Dec. 13, 2001, five armed men in a car drove into the outer fringes of the Parliament compound and opened fire, killing eight security personnel and a civilian. All five attackers, about whom no substantial information has been made public, were soon killed.


According to the police, a trail led from the dead militants to Mr. Afzal and three others — two of whom were also sentenced to death by lower courts, before the Supreme Court, insufficiently impressed by the evidence, overturned one conviction and commuted the other man’s sentence to 10 years.


But the Supreme Court upheld Mr. Afzal’s death sentence, making an observation that would be extraordinary in any mature democracy: “The incident, which resulted in heavy casualties, had shaken the entire nation, and the collective conscience of the society will only be satisfied if capital punishment is awarded to the offender.”


The question is not whether the esteemed court is competent to gauge the “collective conscience of the society” but whether that conscience, whatever it might be, should influence the court’s judgment in the first place. And if it should, then it is hard to overlook a huge body of educated, patriotic and law-abiding Indians who have been saying through all available channels that their “conscience” will be satisfied only if their nation ends the practice of executing people.


Also, there is the matter of inconsistency. There are people who have been sentenced to death for assassinations or for waging war against the state who have yet to be hanged, even though they were sentenced long before Mr. Afzal was. There is no logic that explains why one man in India must hang before another man. The state can, through the sheer force of technicalities, prolong the life of a person on death row, while in a less fortunate person’s case using its discretion to rush through the formalities. In this way, political calculations have been allowed to seep into what should be a purely judicial process.


Indian courts are supposed to impose the death penalty only in the “rarest of rare” cases. But this qualifier has proved to be highly subjective. Recently, the Supreme Court spared the life of a man who had killed his wife and daughter while out on parole; he had been in prison for raping that daughter when she was a minor. The court believed he could be reformed. A few days later, another Supreme Court bench sentenced a man to death for the murder of a 7-year-old boy, having taken into account the fact that the boy was his parents’ “only male child.”


There is outrage, of course, over the implication that those parents’ anguish would have been less, and therefore the crime less heinous, if the child had been a girl.


But there are times, it appears, when the Indian justice system does not wish to satisfy “the collective conscience of the society.”

Gadgetwise Blog: Q&A: Replacing the Motherboard Battery

My ThinkPad laptop asks me to reset the date and time each time I boot up. Why?

Although there could be software issues involved, the battery on the motherboard may be weak or dead. This battery — sometimes referred to as the backup battery, BIOS battery or CMOS (complementary metal oxide semiconductor) battery — supplies power for the computer to retain basic settings like time and date.

Replacing the CMOS battery may fix the issue. If you do not feel like paying a computer-repair shop, you can do it yourself. You need to buy the correct replacement battery (less than $10). Open up the laptop’s case so you can swap in the new power cell. Lenovo’s support site has online manuals for most ThinkPad models that show the location of the CMOS battery. Third-party repair sites like iFixit offer illustrated guides for some laptops as well.

Well: Getting the Right Dose of Exercise

Phys Ed

Gretchen Reynolds on the science of fitness.

A common concern about exercise is that if you don’t do it almost every day, you won’t achieve much health benefit. But a commendable new study suggests otherwise, showing that a fairly leisurely approach to scheduling workouts may actually be more beneficial than working out almost daily.

For the new study, published this month in Exercise & Science in Sports & Medicine, researchers at the University of Alabama at Birmingham gathered 72 older, sedentary women and randomly assigned them to one of three exercise groups.

One group began lifting weights once a week and performing an endurance-style workout, like jogging or bike riding, on another day.

Another group lifted weights twice a week and jogged or rode an exercise bike twice a week.

The final group, as you may have guessed, completed three weight-lifting and three endurance sessions, or six weekly workouts.

The exercise, which was supervised by researchers, was easy at first and meant to elicit changes in both muscles and endurance. Over the course of four months, the intensity and duration gradually increased, until the women were jogging moderately for 40 minutes and lifting weights for about the same amount of time.

The researchers were hoping to find out which number of weekly workouts would be, Goldilocks-like, just right for increasing the women’s fitness and overall weekly energy expenditure.

Some previous studies had suggested that working out only once or twice a week produced few gains in fitness, while exercising vigorously almost every day sometimes led people to become less physically active, over all, than those formally exercising less. Researchers theorized that the more grueling workout schedule caused the central nervous system to respond as if people were overdoing things, sending out physiological signals that, in an unconscious internal reaction, prompted them to feel tired or lethargic and stop moving so much.

To determine if either of these possibilities held true among their volunteers, the researchers in the current study tracked the women’s blood levels of cytokines, a substance related to stress that is thought to be one of the signals the nervous system uses to determine if someone is overdoing things physically. They also measured the women’s changing aerobic capacities, muscle strength, body fat, moods and, using sophisticated calorimetry techniques, energy expenditure over the course of each week.

By the end of the four-month experiment, all of the women had gained endurance and strength and shed body fat, although weight loss was not the point of the study. The scientists had not asked the women to change their eating habits.

There were, remarkably, almost no differences in fitness gains among the groups. The women working out twice a week had become as powerful and aerobically fit as those who had worked out six times a week. There were no discernible differences in cytokine levels among the groups, either.

However, the women exercising four times per week were now expending far more energy, over all, than the women in either of the other two groups. They were burning about 225 additional calories each day, beyond what they expended while exercising, compared to their calorie burning at the start of the experiment.

The twice-a-week exercisers also were using more energy each day than they had been at first, burning almost 100 calories more daily, in addition to the calories used during workouts.

But the women who had been assigned to exercise six times per week were now expending considerably less daily energy than they had been at the experiment’s start, the equivalent of almost 200 fewer calories each day, even though they were exercising so assiduously.

“We think that the women in the twice-a-week and four-times-a-week groups felt more energized and physically capable” after several months of training than they had at the start of the study, says Gary Hunter, a U.A.B. professor who led the experiment. Based on conversations with the women, he says he thinks they began opting for stairs over escalators and walking for pleasure.

The women working out six times a week, though, reacted very differently. “They complained to us that working out six times a week took too much time,” Dr. Hunter says. They did not report feeling fatigued or physically droopy. Their bodies were not producing excessive levels of cytokines, sending invisible messages to the body to slow down.

Rather, they felt pressed for time and reacted, it seems, by making choices like driving instead of walking and impatiently avoiding the stairs.
