@agile Oops, sorry — I didn’t see this question!

I’ve used Karabiner-Elements to set up the Meh ( ⌃ ⌥ ⇧ ) modifier when holding R or U. Then I’m using Raycast to set hotkeys (using Meh+Letter) for important apps. There are probably a bunch of apps (especially launchers) that can do the last job, though! (One nice thing in Raycast is that hitting the hotkey again hides the app. But that might be the case everywhere.)

How’s BTT going?
