Magic Mouse Double Tap > Key Sequence Trigger - Not Working

So I want to have a key sequence triggered with Magic Mouse Double Tap.

Currently, I have the key sequence as Command + W (close window) but this is temporary as I have a different key sequence I want to use but was testing with this simple one first.

Here are my relevant settings:



But when I double tap on Magic Mouse, even though I have HUD confirmation of Key Sequence being triggered, it does not actually close any current window with the Command + W key sequence.

a key sequence is a trigger not an action. In your example you could assign an action to your key sequence that would be executed when you press cmd w

What you want is sending a keyboard shortcut, to do that you can assign a simple action to your 3 finger double-tap:

Yes, I see my mistake now.

But my issue with using keyboard shortcuts is that it won't work with just a combination of modifier keys.

My real use of Double Tap on Magic Mouse is to trigger something like Option + Tab. But since both of these are modifier keys, I cannot use the keyboard shortcuts. Is there any other way?

tab is not a modifier key (only shift (& capslock), cmd, ctrl, opt and fn are). If you really need to just trigger modifier keys you can use the dedicated actions for these:

Ah, so with dedicated actions I could have a combination of Option Down, Command Down, Option Up, Command Up and it would act like if I pressed Option + Command and let go?

correct!

Awesome. Thank you for clearing all of that up.
