Vim short binding for | doesn't work

Question

Trying to map horizontal maximize to something two keystrokes less, but none of these works:

nnoremap \\ | \" Maximize horizontally
         


        

Answer 1

The bar character | is a command separator in Vim script. To use it in a mapping, use <Bar>:

nnoremap <Leader>\ <C-W><Bar>

The relevant documentation is at :h map_bar.
