I've successfully written a number of keymap files, and I

My Problem: I often use multiple keymaps, one after another, and
sometimes I need to switch from using the currently active keymap,
whatever it might be, back to the neutral keymap (or lack of a
keymap). CTRL-^ toggles me back to the previous keymap, which
might not be the neutral one.
Question: How do I explicitly "turn off" keymap usage? or 'set
keymap' to some neutral value?
According to ":help keymap", the default is "", so either
:set keymap=
or
:let&keymap = ''
should do it. I don't know anything about keymaps, so I haven't
verified this.
HTH,

I had already tried
:set keymap=
and
:set keymap=""
without success. But your
:let&keymap=""
(adding a second double quote) worked.
Many thanks,
Ken
The results of
:set keymap=
and of
:let &keymap = ""
ought to be identical. (For the record, what Gary proposed wasn't
:let &keymap = "
with one double quote, but
:let &keymap = ''
with two single ones, which should also give the same result.
Note that since 'keymap' is a buffer-local option, it is recommended to
set it using ":setlocal" if you want to set it for one file without
clobbering other present and future files' setting.
In Normal mode, Ctrl-^ has a different meaning. To toggle (from Normal
mode) whether keymaps will apply (in the current buffer) to the argument
of r f t F T etc. (as well as the next time you start Insert mode), you
can use
:let &l:imi = !&l:imi
(see :help 'iminsert')
assuming that you aren't using an Input Method (you cannot use both an
IM and a keymap in the same buffer at the same time anyway).
I have found the following mappings useful:
" F8: toggle keymaps
:map <F8> :set &l:imi = !&l:imi<CR>
:map! <F8> <C-^>
(especially on keyboards like mine, where Ctrl-^ can only be reached by
holding down both Ctrl and AltGr while hitting unshifted 6).
Best regards,
Tony.
