From the Learn Something New department:

1) If you're using Windows Remote Desktop to work on a remote windows computer, and you want to ALT-TAB, you'll find the ALT-TAB occurs on your PC instead. This is a problem, especially if there are mouse issues and you can't use the mouse to navigate. I found a solution to this:
Instead of pressing ALT-TAB, use ALT-PageUp and/or ALT-PageDown. WONDERFUL! And, to give credit where due, I learned this at http://www.tipicalcharlie.com/swapping_windows_with_remote_desktop.htm

2) If you order steamed dumplings for lunch, and then let them sit for an hour before you actually eat them, they aren't very good.
