I'm surprised to not find any mention on the internet of anyone working around the twiddler's lack of a scroll wheel. I was hoping I could configure the mouse to turn into a scroll wheel when one of the modifiers is down, or at least bind a raw hid code to some chord, but I'm stuck.
I've got my twiddler on the backspice layout now, with some minor tweaks. I was sad to discover the joystick and mouse buttons aren't configurable at all. I looked into hid codes some more, and remembered that wheel up and down are actually one event or something, with a signed char, positive and negative for up and down. Is it even possible to generate wheel events from the twiddler?
I need to stop reading docs now until my headache goes away, but on the bright side, my typing speed has improved just from writing this
PS: pgup/pgdn aren't enough for me - on some apps they scroll a bit too far.
