Hold down ALT and left click an available Hotkey. A user input box will open. Hotkey Line #1 and #2 are used for identifying what the hotkey will do (This is what the jock will see). The information to actually control the switcher is filled out in the Hotkey CatCode section. Use the following code [T]ID01 or [X]ID01 - The [T] or [X] is for toggle and the ID01 is for the aux name created in the Aux Events page and configured in the Audio Routing table. Note: [T] allows only one channel to be turned on at a time where as [X] allows multiple channels to be turned on.
