I sent too soon. I meant

:inoremap <F12><F12> <C-O>:let &iminsert = &iminsert ? 0 : 2<CR>

if you use an ΙΜ (Input Method) in your system and not a Vim
keymap. CTRL-^ won't help you in that case.

I can't imagine what it would be otherwise. If I imap a letter
sequence like FEM it works even when I have my BetaCode keymap on
and typing FEM would normally give me φεμ, OTOH there is no way I
can type FEM/φεμ in insert mode anymore! Then it hit me you may
need to increase 'timeoutlen'. If I :set timeoutlen=1000 (the
default) such a mapping does *not* work anymore: I get Greek
letters and the mapping doesn't fire. With my usual :set
timeoutlen=5000 the mapping works. The downside (which I'd come
to be so used to that I'd forgotten about it!) is that there is a
noticeable delay when typing with a keymap. I have a neurological
disability which causes me to move rather slowly, so it's
probable that for you such mappings will still work with some
lower timeoutlen setting (the documentation recommends :set
timeout timeoutlen=3000 ttimeoutlen=100 which is still sometimes
too low for me but higher than the default :set timeoutlen=1000.

see

:h ttimeout

and *if* you're using an IM

:h 'iminsert'
:h i_CTRL-^
:h xim if you are on Linux
:h global-ime if you are on Windows

Hope this helps!
