Paul: NICE!

Lectric: Alt-F6 switches between windows of a program. Ctrl-F6 switches between windows inside a program window. Try it with multiple Firefox, Microsoft Word, or Adobe Acrobat windows. Ctrl-Tab used to do the job nicely, but hardly works anywhere anymore. And don't forget to add the Shift modifier to go backward through the set.

I'll never forget how Word 6 showed all the shortcuts for windowing (minimize, maximize, restore, size, move) in the Alt-Space menu ("minus menu" from Win 3.1, currently the program icon at left of the title bar). Both Ctrl and Alt for F5, F7, F8, F9, and F10, I think, but it's tough to remember. That's why the famous Alt-F4 is close; just another windowing function.
