General Hotkeys
A hotkey command is a short keyboard sequence for selecting a computer, activating computer scan, etc. The KVM interprets keystrokes for hotkeys all the time. A hotkey sequence starts with a Hotkey Leading Code followed by one or two more keystrokes. After the Hotkey Leading Code is detected, the KVM will interpret keyboard commands until the end of the command.
Note 1: For hotkeys a USB-HID compatible keyboard/device must be connected to the white USB-HID ports.
Note 2: Gaming peripherals or other devices may not work in USB-HID, if so just plug it into one of the blue USB 3.2 Gen 1 ports.
Note 3: Don’t use the Num pad on the right side of your keyboard, use the top row instead.
Possible Hotkey Leading Codes:
- L-Ctrl
- R-Ctrl
- Scroll Lock
