But the *variable* ``b:loaded_tex_ai`` is cleared once I use ``:bd``.
Am I right? (See below.)
There is one error in my description above.
I do not have any trouble with my imaps.
The problem is *only* with my vmaps and maps.
E.g., the following do not seem to clear when I delete the buffer:
map <buffer> <unique> ]] /\\\(sub\)\{0,1}section[[{]<cr>
vmap <buffer> <unique> ;fr "xc\frac{}<esc>"xPla{}<esc>i
And indeed this difference can be tested very easily at the
command line: it has nothing to do with ftplugins and
everything to do with whether maps and vmaps are cleared
when the buffer is deleted. They are not. I thought they
were supposed to be. (See the quoted documents below.)
Specifically, is it a BUG that the buffer is "deleted" but
the map or vmap that is local (!!) to that buffer is not cleared?
(I am not presuming it is a BUG, nor that I have correctly
characterized what is going on; I'm just trying to understand.)

I edit with hidden buffers.
So they are not unloaded when I edit something else.
But this does not matter:
the same errors appear if I do what you say.
This is consistent with the help documents.
Quoting from :h <buffer> ::
Local mappings are also cleared when a buffer is
deleted, but not when it is unloaded. Just like
local option values.
Quoting from :h :bd ::
Actually, the buffer isn't completely deleted, it is
removed from the buffer list |unlisted-buffer| and
option values, variables and mappings/abbreviations
for the buffer are cleared.
