Moving image commands to one submap

Moving image commands to one submap

[Lars Ingebrigtsen]

When the image keymap was introduced, it only had a couple of commands,
so triggering something by accident wasn't a major worry.  But it's now
grown a large number of bindings, so people are hitting these commands
more by accident.

So I think we should move them all under one prefix, to make this less
likely, and also then make the applicable commands use repeat-map.  For
instance, `+ + +' would become `<something> + + +' etc (to increase the
size of an image).

But what should <something> be?  Something with "image" mnemonics and
simple to type, but `C-i' isn't an option (because of confusion with
`TAB').

C-c C-i C-m C-a C-g C-e ?

This seems to be a more general question than just image commands.
There should be a prefix available for all keymaps which are used as a
text property and want to be polite, I think.

How about “C-x .”, “C-c .” or something like that?

PS: I put the Python import commands under “C-c C-i”, which, among
potential issues, display as “C-c TAB” on the menus.  So if someone
finds that bad, please complain in due time.

Thanks, thanks.

It's a bit awkward to type `C-x . +' for instance...

Our long term plan is to try to fix this issue (so that things show up
as intended for `C-i' and `C-m') -- there's several ideas, but nobody's
gone ahead and done it yet.  So I think it's fine to use `C-c C-i' even
if it's currently a bit wonky.

I can't imagine a need to use self-inserting keys while point is on an image.
So why not just 'i' and then the image keymap with '+ - + - ...'
Or the same keymap directly without 'i'.

I'm not quite sure I understand what you mean -- just use `i' as the
prefix key?  That'd be possible.

Maybe I don't understand the problem.  For example, Dired and many other
modes have keymaps with a lot of plain letters, but there is no problem
with hitting these letters by accident.

The problem is in buffers like Gnus article buffers, where keys like `r'
and `h' have bindings.  And then if you've happened to scroll so that
point is over an image, the commands don't work like you'd expect.

`i' is unbound in Gnus article buffers, so it could be used
for the image keymap.  But still this problem remains for other modes
where it clashes with e.g. Info-index, dired-maybe-insert-subdir...

Ideally, the image commands deserve to have own prefix key 'C-x i'.
Currently it's bound to 'insert-file' that is a file-related command.
But file commands also could have own prefix key 'C-x f'.

It's fine to steal some key bindings over certain elements (buttons and
the like) as long as there's not too many of the key bindings -- then it
becomes gradually more and more annoying, as people hit the commands by
accident more and more.

So stealing `C-x i' on images is fine, but something shorter would be
nicer.  Uhm... `#'?  Looks like a frame for a painting if you squint,
like, a lot.

When point is right between the "text before the image" and the image
itself, is it "on" the image?  If the answer is "no", then I agree with
you, but if it's "yes", then I disagree before it's very legitimate to
want to insert text right before an image.

To insert a character before an image, you need to have point on the
image, yes.

I went for `i'.  I tried `M-i' a bit first, but it was a bit hard to
type `M-i + +'.
