- Alt, space, M (press any arrow key), now move active window using mouse = helpful for windows that went off the screen.
- Alt, V, D = view current folder with details
- Alt, space, N = minimize current window
- Alt, space, X = maximize current window
- Alt, space, R = restore current window to previous size
- Ctrl + Shift + ESC = task manager (win2k, winXP)
and many others I can't remember off the top of my head (I'm using a mac right now so PC mode is turned off in my brain)
