I'd like to bind a shortcut to raise/lower windows per screen, not the stacking order or the whole desktop. Is there anyway to achieve this; config files, programmatically, anything?

I stumbled upon the 'window behavior' settings which allows you to bind a modifying key such as 'alt' to mouse buttons. I bound 'alt' to lower/raise window and it seems to be working. However, I would like more control, such as binding to the mouse wheel tilt actions, and cycling forward and backwards through the apps, per screen.

I can't find a place in system settings for configuring the mouse wheel tilt buttons.
It also looks like it doesn't provide a shortcut option for switch/walk through windows of the current screen only.
Suggest filing feature requests for these.
