Middle click to "go here" is a
convention from scroll bars dating back
to the dawn of X11. Using something easily done accidentally (and
unknowingly) for learn doesn't seem like the best idea to me.
That said, some laptops don't have middle buttons...
I think most modern apps use middle mouse button today for midi
connection. Laptops witch didn't have a middle mouse button often even
didn't have a midi in connection so there is nothing to loose.
And, for that case one can provide a midi table to choose connections
from.
Plug in an external interface (like basically everyone does) and it has
a midi connection. Also, jack doesn't need a midi hardware device to be
useful.
A click to "go here", seems on the other
hand like a bad Idea for me.
Most time you have a underling adjustment witch have a much wider range
then the screen counterpart (the controller) represent so that it is
impossible to click on a point and get the wonted value.
I'd worry about left/right buttons first, find agreement on basic stuff,
worry about the leftovers later.
But overall, a agreement about the different use cases
of controller
keys will be very fine and useful for the Linux Audio World.
Yes, I'm also very much pro a convention. I don't see any real solution
to the problem that different human interface guidelines create in
general, and it's a real mess on linux or when you want to go cross
platform, but a convention for Linux Audio sure wouldn't hurt.
