Very good idea. Most often I would like to delete such a pair of
surrounding braces after auctex inserted them automatically for
sub/superscripts. Removing braces around one letter sub/superscripts
might be an improvement to electric sub/superscripts.
Actually, I do like the the braces around the sub/superscripts for either
single or multiple letters, which looks more formal in my viewpoint. You
can set TeX-electric-sub-and-superscript to deactive it if you are in such a
case a lot.
If this really bothers you or somebody else, how about the following idea to
implement it? Use another switch, for example,
TeX-minibuffer-sub-and-superscript, if it is turned ON and
TeX-electric-sub-and-superscript IS TURNED ON, then when you input a _ or ^
in a math environment, you will be prompted to type the super or subscripts
in the minibuffer:
a. if only one letter, after press "Enter", there is no extra {} surrounds
it and the cursor will follow it.
b. if more than one letter, then a pair of {} is added and the cursor will
be out of the {}.
c. if empty, then back to normal, a pair of {} is added, the cursor is put
inside the {}, so people can type their own (may be longer) super/subscript?
Or extend the current TeX-electric-sub-and-superscript to FOUR modes:
0 -- As the current status, turn it off, users type {} as they like in the
Emacs buffer directly.
1 -- As the current status, add a {} after _ or ^ always, and put the cursor
inside the braces.
2 -- Use the minibuffer to type the super/subscripts and add the {} only for
multiple letters; cursor will be placed after your input or }; emtpy or
white space input to the minibuffer will go back the normal buffer and
operate same as 0 (not sure whether it is useful or not, but no hurt at
least?)
3 -- Use the minibuffer to type the super/subscripts and add the {} only for
multiple letters; cursor will be placed after your input or }; emtpy or
white space input to the minibuffer will go back the normal buffer and
operate same as 1
For my case, one example is that sometimes I use \textcolor{red}{a big
blahblah paragraph} for a draft file to emphasize some parts in color. When
I try to remove these colored texts, I can find "\textcolor{red}{" easily
and remove them, but the matched closing brace "}" may be difficult.
Sometimes, I'd like to just remove "\textcolor{red}", and keep an extra "{}"
without error. But I do prefer to removing the extra {} as well if some
easy operation can find it and remove it.
