I have a Keyboard Maestro macro bound to Hyper Key + ' but it does not seem to work with BTT.
If I press all the individual keys, then it works.
Same here. I'm running BTT 3.553 with Caps Lock assigned to "Act as Hyper Key."
For what it's worth, @tjluoma, I deleted my CapsLock assignment then re-assigned it and all is working correctly.
