the problem is that in the <esc><left> sequence, terminal Vim
sees "<esc><esc>[D", so the "<esc><esc>" mapping gets triggered
with the side-effect of issuing "[D" (a backwards jump and then a
delete-the-rest-of-the-line). So to distinguish them, you need
to tell how much time goes between the "<esc><esc>" and the
"<esc><left>" which is done via 'timeoutlen'. I'd just reach for
another key rather than messing with <esc><esc>.

Personally, I tend to add the functionality to control+L which
does a refresh anyways:

:nnoremap <C-L> :noh<cr><C-L>

if you don't have it or use it, the issue is somewhat moot there. :-)
