caps-lock to hyper key doesn't work

[CraigglesO]

I might be doing this a bit wrong, but I want caps lock to be delete if pressed alone, but hyper key if pressed with other keys. When I play in Ukelele I see that its working to the point that I see the hyper key map, but it doesn't listen to the following keypress that joins with caps_lock.

May need to add some modifiers to from.modifiers.optional. Perhaps, caps_lock or any. I am not sure.

[CraigglesO]

Appreciate the suggestion, but I don't think that's it (edited with optional any). If I bind caps_lock to ONLY "left_option" and bind keys to "left_option"+"key" it works.

It seems like the issue is when I have key_code + modifiers for my "to"... I hope I'm wrong.

[MuhammedZakir]

What does EventViewer show when you press caps_lock+<a key> after the modification?

[CraigglesO]

It's definitely working for Karabiner. If I do mapping via Karabiner it works

I'm starting to wonder if it's a bug with MacOS/Ukelele? I'm not going to figght it. Just going to create all the mappings I want this way.

I appreciate your time though.
