org-read-date: selecting date with mouse-2 in calendar

[Michael Heerdegen]

Hello,

selecting a date from within `org-read-date' from the calendar works
with mouse-1, but not with mouse-2 (with latest Emacs master and my
settings loaded at least).

The code seems to intend that it also works with mouse-2, but it fails.

I don't prefer mouse-2, but it would be good to support it I think,
since "clicking" in Emacs is with mouse-2 historically, breaking that
might cause inconvenience.

Why it doesn't work?  Oh, that's because calendar already binds
down-mouse-2 to pop-up a menu (see definition of `calendar-mode-map').
So when we would add the following line to `org-read-date' (it's obvious
to where and I'm too lazy to create a patch now):

+  (org-defkey map [down-mouse-2] nil)

it works as expected for me.  Nothing is lost since the original
popup-menu for the calendar is still being bound to down-mouse-3 (the
more expected key for such a menu in my opinion, at least 2021).

So please consider to add the above line to the defun of
`org-read-date'.


Regards,

Michael.
