Since I have an encoder on my newest keyboard, I try to find some use for it.
On the default layer, it moves the cursor left and right. I'm experimenting with inverting the control mod to move quickly word by word unless I press Ctrl. Pressing the encoder toggles a scrollwheel mode.
On other layers I have the obvious functions
- volume
- brightness of laptop screen, or of external monitor with Shift (with DDC protocol)
- keeb backlight
- brightness of indicators (for layers, caps word, special modes...)
It's fun to configure all this but then I find that I don't remember that it's there and don't use it much.
