I use Remote Desktop all day at work. It is especillay helpful when writing documentation. One of the problems I always run into is trying to remember which keyboard short you can use to capture a screen-shot in a TS session. Since I had to dig these up again today I decided to post them here where they are easy (for me) to find.
Shortcut key Description
ALT+PAGE UP Switches between programs from left to right.
ALT+PAGE DOWN Switches between programs from right to left.
ALT+INSERT Cycles through the programs in the order they were started.
ALT+HOME Displays the Start menu.
CTRL+ALT+BREAK Switches the client between a window and full screen.
CTRL+ALT+END Brings up the Windows Security dialog box.
ALT+DELETE Displays the Windows menu.
CTRL+ALT+(-) Places a snapshot of the active window, within the client, on the Terminal server clipboard
(provides same functionality as pressing PrintScrn on a local computer.)
CTRL+ALT+(+) Places a snapshot of the entire client window area on the Terminal server clipboard
(provides the same functionality as pressing ALT+PrintScrn on a local computer.)
NOTE: for last two commands use the symbol on the numeric keypad without the ().
