I have a Mac. When I try to set the knob to zoom in and out on the Keychron Q Knob version on VIA, it doesn't work. Via doesn't give any keybinding options for it.

1. Please check if your VIA and keyboard firmware is the latest version. If not, please download the latest VIA here and firmware here, or you can use online VIA.

 

2. Zoom in code: {KC_LGUI,KC_EQL}   

Zoom out code: {KC_LGUI,KC_MINS} 

Please click on the "MACROS" tab, and enter {KC_LGUI,KC_MINS} and {KC_LGUI,KC_EQL} in "M0" and "M1" respectively, and save them.

 

3. Please click on the "KEYCAP" tab, and enter "MACRO(0)" and "MACRO(1)" in "Rotate Counterclockwise" and "Rotate Clockwise" respectively.
