Map for maximizing sub-window vertically

How to map this sequence of keys to F3 in Vim: <Ctrl>+W 9 9 9 +? 开发者_运维百科That's sequence for maximizing current :sp window over the whole screen.

I would probably use :

:noremap <F3> <C-W>_<C-W>\|

Where :

• <C-W>| maximizes horizontally
• <C-W>_ maximizes vertically

See :help window-resize for other possibilities.
