Looking over this -- I think it might fit better if we add this to
the keyboard mapping. We already have support for making keyboard
input emit button presses with the 'M' entry, for example like we
have in /sys/lib/kbmap/mouse-csa
# Use left Ctl, Start, Alt as mouse buttons (useful on laptops)
0 29 M1
2 91 M2
0 56 M3
either extending it to allow an 'R' entry, or to allow buttons to sho
up in the central column, would probably make sense; either:
0 29 R321
or, making the mouse buttons availale in the scan code column:
shift M1 M2
shift M2 M1
Since we now support opening the kbmap with OAPPEND, so we don't
clear it on a write, you could have:
/sys/lib/kbmap/mouse-shuffle
that you add to any keyboard map with:
cat /sys/lib/kbmap/mouse-shuffle >> /dev/kbmap
For the 'R' message approach, I have an entirely untested and likely
very broken sketch that I think might be a start; in addition to
making this code actually work, we'd need to adjust the corresponding
keyboard map to keep the shift swapping in place by default.
For the multiple M message approach, we'd need to be careful, I'm not
sure what happens when you have a mapping from A to B, and then B to A.
