bug#24379: [PATCH] lisp/bindings.el: Bind (yank-pop -1) to M-Y

[Nils Berg]

Some healthy discussion here, so let me preface this by saying I appreciate all of you working to keep the default bindings useful and not excessive.

That said, I still feel there should be a single binding for (yank-pop -1). Here's why:

First, all of the other commands that traverse something (that I can think of) have an opposite bound to an equally convenient combination.

C-n/C-p and C-f/C-b, C-v/M-v, C-s/C-r are some examples off the top of my head.

Of course 'M-- M-y' works, but that's like saying 'M-- C-n' does the same thing as C-p. 

(As a side note, I'll admit I didn't actually know/remember M-- is a shorthand for 'C-u -1'. That does make the common case of overshooting the item you want by 1 a lot less painful.)

Second, I fully agree with Clément that just because a command is trivial, it's automatically unhelpful to bind it. Again, see C-n/C-p.

And lastly, if a user has a custom binding for M-Y or C-M-y (I'm not dead set on either), that will still prevail.

I don't see why they'd be any more reluctant to override those than M-y, which you said lots of people do.

It's pretty hard to google "M-y", much less "M-Y", without Google deciding I'm actually looking for "my", so I'm going to trust you on that.

So that's my 2 Cents. If you're still unconvinced, feel free to close this :)

Maybe you're having trouble because you're trying too hard to
argue. ;-)

Many users do override default bindings.  And many do not.

In any case, the proposal was about `M-Y', which is not bound
by default.

It's a trivial command, which is not hard for a user to discover
or consider binding.  And as you yourself pointed out, `M-- M-y'
does the same thing.

You're trying too hard to pick a fight, I'm afraid.

Do _you_ think `M-Y' should be bound by default to the suggested
command?  If so, please present some supporting arguments.
