Hey Peter,
Things didn’t work out so well for me on this end. I’m using a MacBook Pro, Mac OS X Version 10.7.5.
You stated the path below:
/Users/[username]/Library/Application Support/Adobe/Premiere Pro/6.0
When I follow that path on my computer, there isn’t a “Premiere Pro” folder inside of the “Adobe” folder. I tried to create a new keyboard layout with a distinct name so that I may search for it much easier but no results populate.
What could be the problem? Thank you!
