Shortcut World has a nice compilation of keyboard shortcuts for Firefox, Word, Excel, WindowsXP and our old favorite PowerPoint. As a presenter, consultant and teacher I have to admit that I have some favorites.
I love the B key and W keys for displaying a black or white screen when I'm presenting. I tell people when using PowerPoint these are among the most powerful keys because they move the attention where it should be - on you and what you're saying not on the PowerPoint slides. For some keyboard shortcuts, I find the alternative navigation to these commands to be almost as fast and easier for me to remember or see in the open window.
I also like the alt tab key combination in windows to move forward between the windows that I have open with Windows XP.
So what's your favorite shortcut?
