Do you have a touchpad with up/down or left/right buttons?

[Peter Hutterer]

Some (mainly older ones, afaict) touchpads have additional buttons to the
usual LMR set. These buttons are usually used for up/down and left/right
scrolling.

Something like this:

If you own a laptop with such a touchpad, please contact me off-list, I'd
like to get some logs from you.

Cheers,
