I like using my rotary encoder to prune tabs, what do you do with yours?

My Keychron Q11 showed up recently and I've been super happy with it. Main reason was that my Noppoo Choc Mini finally lost a switch and I don't have any on hand (nor a soldering iron ...yet) but it turns out I actually really wanted the pair of rotary encoders on this and didn't even realise.

Specifically, I've got it bound to Ctrl-PgUp/PgDown so I can scroll through my tabs with it and close them with a click binding to Ctrl-W and that's working out really well.

Anyone else use the knobs like that? I've got the other one set to volume and the vendor had zoom as a suggestion but I wonder what else people do with these?


Bonus newb Q: On the product page they demonstrate binding Ctrl-+ zooming to the encoder via a macro but neither macro13 nor the {KC_LCTL,KC-W} type syntax would let me click "Confirm" when trying to associate it to the knob in Via (eg. it wouldn't let me follow their example). Luckily it was happy with the alternative of LCTL(KC_W) that I stumbled on somewhere but now I wonder how to properly associate a macro to a knob?
