- Copy the file
plugin/toggle_mouse.vim
to your~/.vim/plugin
directory - There is no step 2.
Press <F12>
to toggle mouse focus between Vim and your terminal emulator,
allowing terminal emulator mouse commands, like copy/paste.
Toggling restores the Vim 'mouse' option value to its previous value.
If you don't want to use the <F12>
key for mouse toggling, simply remap it to
another key. It autodetects whether it has been remapped and won't register
the <F12>
key if so.
