Ok, so, unlike Bome's, AHK will actually not pass on a regular "F message" to Live? That's cool, and I will try it.
I was leaning towards Bome's in the first place because I wanted to try to move the Launchpad control frame in Session view, simultaneously updating the Launchpad, with keyboard keys - 8 tracks/scenes at a time, as this takes two button presses on the LP, but no luck...
I'll give AHK a go, but I still wish Ableton would remove the necessity for 3rd party apps JUST to free up keys for mapping. For more complex things, sure, but keeping the F keys locked like that is silly.
