Feature Request: Control keypresses sent on lock

[LRitzdorf]

When the chosen "lock button" is pressed, the OnlyKey locks itself and sends the Super+L key combo to the connected device. This key combination is not always desirable — on my Linux/i3 setup, for example, this changes my active window. Accordingly, the ability to control which key combination is generated when pressing the lock button would be helpful. (Maybe this could use the same keyboard syntax as SysAdmin Mode?)

While I realize that not many people have such customized setups, I would guess that OnlyKey users are more likely to than the general population, so this feature would be a notable quality improvement.
