Hot-key commands
A Hot-key command is a short keyboard sequence for selecting a computer, activating
computer scan, etc. A hot-key sequence starts with two left <CTRL> keystrokes
(successively within 0.2 seconds) followed by one or two more keystrokes. A highpitch beep will be generated for each correct hot-key command; otherwise, one
low-pitch beep is generated for errors and the bad key sequence will not be forwarded
to the selected computer.
NOTE: Left <CTRL>: refers to the Control key on the left side of the keyboard.
1~8: refers to the number keys ‘1’ through ’8’ in the upper row of the keyboard. Do
not use the numeric keypad at the right of the keyboard for entering numbers for any
hot-key command.
To select a computer by hot-key command, you must know its port number, which is
determined by the KVM switch connections.
