I'm redirecting this conversation to vim_use which I think is more appropriate
than vim_mac in this case.

If you don't want to hold both Ctrl and Alt, well, choose some other {lhs}.
Here is an example, but it is thertainly not the only possibility:
:map <F6> <C-W>h
:map <F7> <C-W>j
:map <F8> <C-W>k
:map <F9> <C-W>l
Or if Ctrl-W is easy for you to type, just use it instead of :wincmd, that's a
built-in key binding (in Vim compiled with +windows, of course), no mapping
needed.
See :help :wincmd
What I use is, navigate to the next or previous window rather than
geographically, as follows:
" move to next window with F11, previous window with Shift-F11
" These will accept a count (in Normal mode at least)
" to go to Nth window from top, not Nth previous or next window
:map <F11> <C-W>w
:map <S-F11> <C-W>W
:map! <F11> <C-O><C-W>w
:map! <S-F11> <C-O><C-W>W
Best regards,
Tony.
