How to set Vim's Local Leader to Backslash?

Question

This works fine for setting local leader to the minus key:

:let mapleader = "-"

I can't figure out how to set it to backslash. I've tried the following with no avail:

:let mapleader = "\"

:let mapleader = "\"

:let mapleader = \

Any help is greatly appreciated.

Answer 1

Either escape the backslash or use single quotes:

:let mapleader = "\\"
:let mapleader = '\'
