Yes indeed.  I brought this up when we were in the keyboard design
phase, but it was determined, quite fairly, to be too much effort for
the overall gain, given the other components of the system and state
of the software (both then, and now, for that matter).  It seems that
in the future this is a wise place to spend a little extra time, since
it could actually have some high energy saving benefits if done well.
Naturally, we could provide a way to turn the mode off in the control
panel for that that don't want that kind of micromanagement.
