Keyboard Keys
Backspace
With most applications the
←
(Backspace) key moves the cursor to the left one space at a
time, erasing any character it passes.
Ctrl
The keyboard has two identical Ctrl (Control) keys. With many applications the Ctrl key
changes the function of another key when both keys are pressed simultaneously. For
example, under MS-DOS, pressing the Ctrl-Pause keys sends a Break signal to stop
execution of the current program.
Alt
The U.S. keyboard has two identical Alt (Alternate) keys. Like the Ctrl key, the Alt key
generates an alternate function for another key in many applications.
Fn
With many applications the Fn (Function) key is used to access numbers, characters, or
the functions printed in blue on the fronts of some keys on the TravelMate 3000 keyboard.
SysRq
The function of SysRq (System Request), produced by pressing the Alt-PrtSc keys, varies
by application program. Not all programs use this key; check your application program
documentation for details.
Prtsc
With many applications pressing the PrtSc (Print Screen) key causes your printer to print
whatever is displayed on the screen if your printer is connected, turned on, and online.
