I can remap unused combinations like
<d-1> (Cmd+1) in MacVim, but there are many combinations like
<d-b> that are already bound to MacVim menu items. If I try to remap those inside my .vimrc, nothing changes.
Is there some way I can remap those combinations inside MacVim, or stop MacVim from assigning them to menu items so they are properly passed on to the Vim core?
