Hm, we need to review how many apps have hijacked Middle_Mouse for
controller registration. I thought Ardour had done this, bristol has: if you
click middle mouse then I register the next MIDI CC so the control tracks
that CC. I think Ardour might use (used to use?) Control-Middle_Mouse
for this purpose. No objection to either approach if 'enter a value' is
the target here for Middle_Mouse on its own.

Personally I don't think the underlying unit should define the steps with
Control/Shift: I viewed them as going min to max in a given number of
keypress/repeats irrespective of the quantisation. If it is not done as a
fraction of the full throw of a control then it might just end up as being
another arbitrary set of definitions?

Glad you said that. I prefer the GUI to have equal steps. The backend
needs to decide if they have to be lin/log.
