:help i_CTRL-G_CTRL-G and
:helpgrep CTRL-G more generally and can't figure out why
<c-g><c-g> is equivalent to a
<nop> in insert mode.
For some context, I was having problems with the mapping:
nnoremap ` <nop>
And it was suggested in a comment here: Using a no-op key in insert mode, can't use key after using no-op mapping That I should use
nnoremap ` <c-g><c-g>
Using this workaround the problem is avoided, but I can't figure out why it works. In particular, I'm trying to understand how
<c-g><c-g> duplicates some or perhaps all of the observable behavior of
<nop> ... while simultaneously hitting a different enough codepath to avoid triggering the bug.
