Hello, I think I've sent a bugreport about this in every version since it came out. And I feel that it should be easy enough to solve
But in fairlight you have different modes for selecting and general editing of the audio clips in the timeline. And the lastest mode they added (it's a couple of versions back now) is called "focus mode". Very handy mode for editing but sometimes you need to switch the modes and it's really frustrating to be able to use shortcuts for some of the modes but not the "focus mode". Come on now!

Add a shortcut option and be sure to make it customizable as well
Cheers
