Somehow I think it is two different kind of things. We already have two ways of 
changing the parameters:
* "static" : it is currently set with the paintop widget (I think of brush 
radius, fade...)
* "dynamic" : changed while painting using the information from 
KisPaintInformation coming from mouse/tablet events

The sensor idea is a solution for the "dynamic" changes, and allow to use 
different things than pressure, and they work on KisPaintInformation. While I 
think the keyboard shortcuts would trigger a change in the static parameters.

Basically, the main use case I see for keyboard shortcuts are:
* increase/decrease the size of a brush without going through the widget (with 
+/- and/or mouse wheel)
* switch between paintop pressets

I am not sure what you mean by that ?

Thinking of spacing, should I add a spacing slider to the autobrush ?
