Using the trackball as a scroll wheel
Opened this issue · 1 comments
As a user of the Ploopy classic and nano trackballs, I would like the ability to hold down a key combination (both forward/back buttons together, for example) which would allow the trackball to act as a 2D scroll wheel, rather than a mouse input.
There are OS-specific solutions like Logitech Marblemouse software or AutoHotKey scripts that can accomplish this, but QMK also has the ability and would remove the OS restrictions and complicated setups.
I probably don't know enough or have enough experience with QMK to help, but I'd imagine this is a pretty common wish for trackball users.
@lacymorrow As far as I am aware, the firmware is a part of the QMK repo. There is a drag_scroll keymap upstream, which is what I'm currently using to make the trackball act as a 2D scroll wheel.
