如何在MacVim中将<d-a>映射到增量1

Question

如何在MacVim for Command-A中获得1行为增量？ <C-A>按照预期的增量递增。在Windows中我只需取消映射<C-A>，所以在MacVim中我尝试了以下内容：

" Doesn't seem to work. <D-A> still selects all
macmenu Edit.Select\ All key=<Nop>
nnoremap <D-A> <C-A>

_

" Doesn't work, no mapping exists
nunmap <D-A>

我看过以下内容，但我仍然无法弄明白：

how to map command key when configurate .vimrc?

How to increment in vim under windows (where CTRL-A does not work...)

Answer 1

As explained in :help :macmenu,

• you must do that in ~/.gvimrc,
• <D-..> mappings are case sensitive so <D-A> is not the same as <D-a>.

So, in order to use <D-a> in place of <C-a>:

1. Create ~/.gvimrc if it doesn't exist.

2. Add the following lines:

   macmenu Edit.Select\ All key=<nop>
   nnoremap <D-a> <C-a>
