This command seems to have been added in Emacs 27
and immediately given the default key binding of
`C-M-down-mouse-1'.
Emacs 27 is still the latest release. It's likely
that use of this binding isn't yet baked-in for
many users.
I, for one, didn't notice that this had happened
until a few days ago. I didn't see any discussion
/ proposal about this in emacs-devel. But I might
have just missed it somehow. Was this discussed?
IMO, this command should be given a different
default key binding. (I'm not against giving it
a default binding.)
Can we discuss this? I suggest giving it the
binding `C-x down-mouse-1' instead. But mainly
I'd like to see its binding taken off of `C-M-'.
Here are my reasons.
I'd be interested in reasons for binding another
key instead - as well as reasons why someone
thinks this really deserves to be on `C-M-'.
1. There are no other rectangular-region
commands on `C-M-', and no plans to put any
others on it.
2. There are sets of related commands that it
could make sense to put on `C-M-'. And there
will be more such, over time.
`C-M-` is too valuable to waste on a single
command (i.e., unrelated to others on `C-M-').
Remaining (unused) `C-M-' bindings should be
saved for related commands (or at least for
commands that are repeatable by just holding
down keyboard keys).
3. `rectangle-mark-mode' is on `C-x SPC'. This
is the other rectangle command that involves
the active region (the only one).
Its behavior is related to that of the command
in question (an alternative, in a way). These
two commands deserve to be strongly associated
by their keys.
The other rectangle commands (which don't
involve the active region) are also on `C-x'.
These associations call for the new command to
be added to the same bunch - same prefix key.
It makes a good deal of sense to put the new,
rectangle drag command also on `C-x'.
Could we please consider binding rectangle
definition-by-dragging to `C-x' instead of
`C-M-'?

(I filed bug #52130 for this, but that was
immediately closed as "won't fix", with the
reason given as just "Well, I think it makes
sense" - presumably an appeal to authority.)
