Ctrl+Alt+Delete in Remote Desktop

Here is a tip that I've found not many using RDC (mstsc.exe, Windows Remote Desktop Connection) know about. Several times I've been asked why Ctrl+Alt+Del doesn't work. The solution is to use Ctrl+Alt+End and you will get access to Windows Security with Task Manager, Log Off, etc.
So, on the topic I might as well post some more keyboard shortcuts:

• ALT+PAGE UP (Switch between programs from left to right)
• ALT+PAGE DOWN (Switch between programs from right to left)
• ALT+INSERT (Cycle through the programs in most recently used order)
• ALT+HOME (Display the Start menu)
• CTRL+ALT+BREAK (Switch the client computer between a window and a full screen)
• ALT+DELETE (Display the Windows menu)
• CTRL+ALT+Minus sign (-) (Place a snapshot of the entire client window area on the Terminal server clipboard and provide the same functionality as pressing ALT+PRINT SCREEN on a local computer.)
• CTRL+ALT+Plus sign (+) (Place a snapshot of the active window in the client on the Terminal server clipboard and provide the same functionality as pressing PRINT SCREEN on a local computer.)
