Add second hotkey to thumb button when Left Ctrl key is held down (MX Master 3S)

I already have a hotkey configured in BTT for the mouse thumb button (MX Master 3S), and it works fine.

I would like to know if it’s possible to add a second hotkey to the same thumb button so that a different action is triggered when the thumb button is pressed while the Left Control (Ctrl) key is held down.

I couldn’t find a setting for this when I was looking.

yes, it works the same as for all other triggers in BTT:
Create a second version of the button and make it trigger only while ctrl is pressed:

Of course. I should have known that. I’m still getting familiar with the UI :grin:
