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.
