I just found out that you can CTRL-ALT-BREAK to go full screen when connecting to a computer using Remote Desktop Connection in Windows XP. Thats always been a pet peeve of mine since maximizing the window goes full screen when connecting to a computer that is running Terminal Services. I figured they took it out for some reason, but it turns out they just buried the command - just a little too deeply if you ask me.
Edit: I guess you could just do options->display->full screen, but who checks there anyway? Besides, whatever happened to good ol' ALT-ENTER?
