Key from bluetooth keyboard recognized but trigger does not activate

Hi there, and thanks in advance for your time.

I've been using Keyboard Maestro for a long time, and this is a recent challenge. I looked around the forum for similar questions but didn't find a problem like this one.

What I want to do

I type a lot of ( and ) in the code that I write. A long time ago I set up Keyboard Maestro so that if I tap the left shift key without other keys or modifiers, it inserts (, and likewise for the right shift key. I love this, it works beautifully and has become muscle memory. Here's how it's implemented:


I started using a bluetooth keyboard and I can't get this trigger to work for it.
I click the green + button and add another device key trigger, click in the box waiting for a keystroke, and the keystroke is recognized. However, tapping the shift keys does nothing.

(the screenshot shows is pressed but the problem persists with is tapped as well, and all other selections from that dropdown)

More details

  • This affects all keys from this keyboard, not just the shift keys.
  • I got other bluetooth keyboard like the Magic Keyboard to work with this.
  • Rebooting does not solve the problem.
  • Currently running 10.14.6 (Mojave) if that matters.

Does anyone have any ideas?
