I would like to use alt+number to navigate tags:
e.g. nnoremap <a-1> 1gt
nnoremap <a-1> 1gt
It does not currently seem to work on 0.11.
<a/c-1> isn't recognized, but for example <a-1> would actually expand to <esc>1 and it should work.
Added <[am]-[0-9]> in this commit. I don't think that corresponding combinations exist for control key in terminals except for <c-6> which is already available as <c-^>.
