Blender does not recognize the BTT Shift modifier

Bugs or Unexpected Behavior

Blender does not recognize the BTT Shift modifier.

Under the Trackpad Menu, I have the 4 Finger Swipe Right gesture assigned to the Custom Keyboard Shortcut [Shift A] which should bring up a menu to add an object. Instead, it toggles the Select/Deselect action which is what happens when you enter [A] without the shift modifier. Can this be corrected?

I ran into the exact same issue; same system settings except I'm on Mojave.

To make matters weirder, I tried creating a shortcut for animation playback, and the Alt+A shortcut would only work if I ADDED a shift modifier in BTT, to make it Alt+Shift+A, so its almost like shift behaviour has been inverted?

Hopefully there's a way around this, BTT almost salvages the Touch Bar for me!

Just to clarify:

Alt-A was not working in Blender, so you added Alt+Shift+A in BTT. So did you set it up so that Alt+Shift+A sent Alt-A to Blender? And did you specify that was just for Blender?

Blender doesn't recognise ANY modifier key, in fact there's no "cmd/opt/ctrl/shift + normal key" shortcut working on BTT with Blender!

I tried some different solutions, like adding modifier keys as actions, for instance for Shift+S, something like:

  • Action 1: Modifier Keys > Shift Key Down
  • Action 2: Keyboard Shortcut "S"
  • Action 3: Modifier Keys > Shift Key Up

Initially it seems to work, but the problem is that BTT looks like it immediately crashes, and I have to restart it! It looks like the trigger doesn’t stop and this blocks BTT.

Currently the only way to make a shortcut like this working seems to be using Applescript. So for the example used above (Shift+S), with “Run Apple Script (blocking)” write:

tell application "System Events" to keystroke "a" using shift down

I hope in the future Andreas will solve this bug, in the meantime it looks like this is the only way to make it work!

I feel like something isn’t working correctly on Blender’s end. I’ve tried different apps (such as pie menu apps) to set shortcuts, but Blender doesn’t recognize them either. For example, if the action is supposed to trigger Shift + Option + O, Blender only detects O as the pressed key, ignoring the modifiers.
