REQ: Trigger for display wakeup

You can subscribe the triggers yourself using AppleScript according to this template:

If the script is started as a file at the start of BTT (important, because otherwise it runs in a script runner, which is terminated after execution), the triggers come reliably.

Edit: Here is the script for NSWorkspaceScreensDidWakeNotification based on the template:

script theScript
	use framework "Foundation"
	use scripting additions
	
	property ca : current application
	property workspaceClass : class "NSWorkspace"
	
	on addObserver()
		set ws to workspaceClass's sharedWorkspace()
		set nc to ws's notificationCenter()
		tell nc to addObserver:me selector:"screensDidWakeNotification:" |name|:"NSWorkspaceScreensDidWakeNotification" object:(missing value)
	end addObserver
	
	on screensDidWakeNotification:theNSNotification
		tell application "BetterTouchTool"
			--trigger your named trigger
			trigger_named "OnScreensDidWake"
		end tell
	end screensDidWakeNotification:
end script

theScript's addObserver()

Note: Of course it does not work if the option "Restart BTT after standby" is activated in BTT. In this case you can directly use the trigger "After BTT was started".
