How to map several keys in Vim

Question

How would I map ctrl+w+o to execute :Bonly<CR> ?

I have tried

unmap <C-W>o
map <C-W>o :Bonly<CR>

Save file and source it with so % , but does not work.

Answer 1

Your mapping (the :unmap is not necessary) should work with a sequence of Ctrl + W , followed by o .

If you want Ctrl + W followed by Ctrl + O , that'd be <Cw><Co> .

In Vim, one can only map Ctrl / Shift / Alt combinations (and not all of them, unfortunately!) with a single key (like W ). But there's a plugin that may help you achieve a mapping of all keys pressed simultaneously: arpeggio - Key mappings for simultaneously pressed keys
