For the love of god please add a very simple 'buttonHeld / keyHeld' or whatever you want to call it.
Command would simply work as follows:

buttonHeld _dikCode where it returns true/false depending on whether giving dikcode button is currently pressed.

This is very helpful way to add extra modifier keys when you're using more advanced UIs.
displayAddEventHandlers messed upup when closing/opening additional displays and dialogs, it also has issues with steamoverlay keybinds and alt+tabbing out of the game.
inputAction doesn't work on dikcode and also has issues with dialogs.
