beep is generated for errors and the bad key sequence will not be

forwarded to the selected computer.

NOTE: Press and hold Left <SHIFT> and press <NumLock> twice,

then release Shift followed by pressing left <CTRL> once, which will

enable / disable the hotkey feature.

To select a computer:

Left <CTRL> + Left <CTRL> + 1
