When using full screen on a seperate desktop, its a pain to switch back to dig through the menus for ctrl-alt-del A key combination would be a HUGE help.
On mine, it is, in this order: ctrl-alt-fn-del Another one: what about the alt-F4 command? It is: alt-fn-F4 Notice that you basically use the same key sequence, but the FN key just prior to the last key.
