Hi, Nico,

I just tested your patch, and unfortunately it doesn't fix the problem I 
have with CTRL-^.  If I understand the patch correctly, it hard-wires 
CTRL-2 and CTRL-6 to their shifted equivalents (CTRL-@ and CTRL-^).  I 
believe the patch does as it is intended because the patched version of 
Vim circumvents my work-around for the still-broken CTRL-^ behavior.

According to the Vim manual, pressing CTRL-^ (that is, ctrl-shift-6) 
should switch to the previously edited file.  On Linux and Windows, this 
works for me, but on my mac it doesn't work; instead, pressing CTRL-^ 
(and CTRL-6, for that matter) behaves as if I'd pressed '6' without 
either shift or control.  So CTRL-^j results in the cursor moving down 6 
lines instead of switching to the previous buffer and going down one line.

My work-around for this problem is the following map in my .vimrc:

" mac-vim 7.206 doesn't properly handle CTRL-^ (and CTRL-6) to
" edit the previous buffer.  This mapping is a work-around.
if has("mac")
    map <c-6> :e #<CR>
endif

When I apply your patch, my work-around no longer fixes the problem, 
since CTRL-6 is hard-wired to CTRL-^, and CTRL-^ itself doesn't work 
properly.

Also, when I'm not using your patch, I'm unable to map CTRL-^ to my 
work-around with either of the following:

  map <c-^> :e #<CR>
  map <c-s-6> :e #<CR>

But when I map CTRL-6 as I've done in my .vimrc, I can use both CTRL-6 
and CTRL-^ to invoke my mapping.

I don't really understand what's going on here, but I'm content with my 
work-around until a full solution can be implemented.

Thanks,
Michael Henry
P.S. I'm using Vim 7.0.206 for these tests.
