Comment:

 I'm not sure if this is semantically correct, but let me propose
 implementing alt-brightnessup and alt-brightnessdown as toggles between
 b&w and color modes.  They are the most logical buttons to associate with
 the display, for sure.

 We could make both brightness keys be on/off toggles, each behaving
 identically. Alternatively, we could opt to choose one or the other so
 there is no redundancy. We could also use alt-brightnessdown to switch to
 b&w and alt-brightnessup to return to color, but I don't see a need to
 split these functions into multiple buttons, rather than making them a
 toggle.  I only suggest making both keys the same so people don't have to
 remember which key it is.

 I recommend using the alt modifier because I want to reserve the primary
 ctrl modifier for a min and max functionality:

  - ctrl-brightnessdown : backlight off/b&w mode
  - ctrl-brightnessup : full brightness/color mode
  - ctrl-volumedown : mute
  - ctrl-volumeup : full volume

 Jim, could you reassign as appropriate?
