Quick Screen Locking
Want to lock your screen quickly before walking away from your computer? About a week ago I accidentally discovered that pressing Ctrl-Alt-L locks the screen in Gnome on Fedora Core 5.
Frankly, that's almost everything I know at the moment. I think this is a relatively new feature. It doesn't seem to work in RHEL4, and I don't have easy access to any other distributions at the moment.
