Thanks again!
It's not really a macro I'm after, I just want to assign a keyboard key/key combination (e.g. Alt+f) to a remote button directly with the SkipApp.
I understand a workaround is to assign a whatever remote signal to a button in the SkipApp and then do the keyboard key assignment with the Flirc App, but a more straightforward solution would be nicer. Your last sentence suggests that is not possible yet?
