Quicksilver is a Mac OS X utility which allows me to use the keyboard to
perform quick tasks, such as launching applications or opening files. Among
many other things, Quicksilver indexes my address book, so I can quickly
find a telephone number or compose an e-mail. When I select a phone number
entry and hit Enter, I see the phone number splashed across the screen.
Why is that useful? I can concentrate on punching the number into a phone
without having to squint at a small address book entry. (BTW, don’t bother
dialing that number: I made it up.)
