binding S-mouse-1

binding S-mouse-1

[Tak Kunihiro]

Keys <S-right> and <S-left> extend region.  I think that [S-mouse-1]
should behave similar by default.

I propose to bind mouse-appearance-menu to super instead of shift,
  (global-set-key [S-down-mouse-1] 'mouse-appearance-menu)
and bind following to let shift click to extend region on mouse.el.
  (global-set-key [S-down-mouse-1] 'ignore)
  (global-set-key [S-mouse-1] 'mouse-save-then-kill)

Isn't that backward-incompatible change in behavior?

FWIW, I use S-down-mouse-1 quite a lot, especially when testing
various display-related bug reports and questions.  Replacing it with
super, for which I have no key on my keyboard, would need both more
customizations and re-teaching my muscle memory.  All that just to
provide some kind of "consistency"?  I'm not sure it's a good enough
reason for changing such a veteran behavior.

Thanks.

This seems to be common behaviour across other applications (e.g.,
Firefox), so it could help with the muscle memory of newer users.
Perhaps we could enable it in cua-mode?

Moving mouse-appearance-menu to super doesn't work since we can't rely
on super being generally usable. Perhaps C-S- instead?

I suppose you meant without customizations, you have to re-teach.  You
do not have to do both.

I think internal consistency between mouse-1 and S-mouse-1 also
matters as well as behavior of S-mouse-1 across applications.

Shift should modify operation by mouse-1.  I think `extend region' can
be regarded as modified set-point; however mouse-appearance-menu has
significant distance from set-point.

How about A or B?

A (global-set-key [C-S-down-mouse-1] 'mouse-appearance-menu)
A (global-set-key [S-down-mouse-1] 'ignore)
A (global-set-key [S-mouse-1] 'mouse-save-then-kill)

B (define-key cua--cua-keys-keymap [S-down-mouse-1] 'ignore)
B (define-key cua--cua-keys-keymap [S-mouse-1] 'mouse-save-then-kill)

Yes, I do have to do both, because I will have to tell Emacs to use,
say, the left Windows key as super, and then learn to use that when I
need the menu which currently pops up by S-mouse-1.

The current binding of S-mouse-1 was not taken out of thin air, it was
modeled on other applications as well, AFAIR.

I don't use CUA, so my opinions about modifying its bindings don't
matter.  We should ask CUA users if they care.

But I don't think we should change the default behavior of S-mouse-1.

+1.

Also, if you do that, you free the right mouse button for some context
menu. (It should probably contain the top seven items of the Edit
menu, and possibly more.)

Additionally, C-mouse-4 and C-mouse-5 could be bound to
text-scale-increase and text-scale-decrease.

I suppose that you also infer consistency across applications.  If so,
targeting applications matter, I think.

How do you think about reason that I inferred, consistency within
Emacs?

Consistency has never been a reason strong enough to change a
long-standing behavior.
