Possible improvement to combo macro

[kovasap]

I used your config as inspiration for my own, and I think I made a slight improvement to the way I define my combos: https://github.com/kovasap/zmk-config/blob/b7ec93c8089a8790ad8184b92261b096e5adecf6/config/corne.keymap#L62

Thought I'd share in case you like it!
