Subject: Re: bug#34014: 25.2; binding down mouse event with modifier to
 mouse-drag-region does not work
Date: Sun, 16 Aug 2020 22:54:37 +0200

Ah yes, track-mouse is almost  what I need, as I said I wrote my
replacement for mouse-drag-track, but the double and triple click
behaviour is tricky in its own right, with all those timeouts and
motion bounds to keep in mind when pursuing the multiple-click
hypothesis, and mouse-drag-track did that all perfectly until Emacs
25, yada yada yada.... A bit frustrating.

Sorry :) Let's try to come to a constructive conclusion. By the way,
Emacs is a great piece of software, and I am slightly ashamed that I
did not contribute to it, given that it is my editor of choice, and
given the numerous Emacs-Lisp goodies that I  use a lot daily, enabled
by Stallman's fabulous basic design.
