Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Quartz code should use F13, F14, and F15 keys instead of PrintScreen, ScrollLock, and Pause, since that's what's on the standard Apple keyboards (minus the laptops, which have neither set). Ideally we'll find a better way to distinguish this...the keys being replaced would be correct on a USB keyboard for Windows. Sigh. Fixes Bugzilla #301.
