Using KPL buttons as dimmers

[SiberianGnome]

I have an 8 botton KPL.  Main button turns on the main load.  I'd like to use buttons C and E as brighten and dim, respectively.  

I've read through the manual and found the little chart that shows how dimming works.  When you press and hold a toggle button, it will fade up.  And then the next time you press and hold, it will fade down.  It will always fade in the opposite direction of the previous fade.

The manual also says that if you have a "non-toggle on" it will always fade up, and a "non-toggle off" will always fade down.

But I can't figure out how to incorporate these into a scene to actually achieve what I want them to achieve.
