Show current <leader> key setting?

I'm having a problem with VIM whereby none of my commands work.

Is there a way I can see what my <leader> is currently set to?

To see the current value currently defined for <leader>, use:

:let mapleader

Producing output like:

mapleader ,

It may be undefined if not previously set, defaulting instead to a backslash \

By default mapleader is not set, and special string "<Leader>" means \.

If you do:

:echo mapleader

you will get

Undefined variable: mapleader
Invalid expression: mapleader

If you want to set special string "<Leader>" to a different key, say ",", which is recommended by many, do:

:let mapleader=","

Then

:echo mapleader
,

Fortunately, map expands <key_name> values in both the LHS and RHS. You can exploit this to see the value of <Leader> even if it is the default value.

:nmap temp :echo('your leader is "<Leader>"')<Esc>| execute 'normal temp'| nunmap temp

Note that if you put this in your .vim/vimrc it will pause with "Press ENTER or type command to continue". Please comment if you know how to fix this.
