<C-,> as well as some other special keys (
<C-S-Space>, ...) in my vimrc like,
:set <F13>=^[[44;5u :map <F13> <C-,> :map! <F13> <C-,>
and configured iTerm to send
<C-,> is typed.
^[ is the ascii Escape character.)
It works great, but Vim flashes
<80>ü^D, in the showcmd area whenever I use
<C-,>. Here's a screenshot (see the bottom-right corner):
It doesn't inhibit the mapping or seem to cause any problems, I'm just curious what it indicates. None of my other special mappings (
<C-Enter> and the like) do this.
Do you know?
