Hi,
the ws(4) mouse driver has the option of emulating the mouse wheel
on motion + a given button is generated.
This is active by default on button 2 on recent Linux systems (those
using libinput).
Should OpenBSD's ws(4) activate it by default too ?
If you want to experiment without rebuilding X you can run the
commands below to enable it
xinput --set-prop --type=int /dev/wsmouse 'WS Pointer Wheel Emulation' 1
xinput --set-prop --type=int /dev/wsmouse 'WS Pointer Wheel Emulation Button' 2
