Hotkey Commands
Hotkey commands are keystroke sequences that initiate computer/device functions and can be used to initiate KVM Switch

keystrokes. Successful hotkey command inputs result in a high-pitched beep. Unsuccessful hotkey command inputs result in a
low-pitched beep.
Notes:
- All keystroke combinations must be entered in rapid succession.
- Press and release the indicated keys, unless otherwise specied.
