See the following, at :help <Leader> and :help <LocalLeader>:

IOW, if you

:let maplocalleader = '_'

then from now on, any _new_ mappings defined with <LocalLeader> will use
an underscore for it, instead of the default backslash.

Whenever a new macro is defined, if it is written with <Leader> in it,
Vim replaces that symbol with the value of the variable named mapleader
(or a backslash if empty or undefined), and if it uses <LocalLeader>,
Vim uses the value of maplocalleader (or a backslash if empty or undefined).

If you later change one or both of hese variables, already defined
mappings are unaffected; the value used is always the value at the time
the mapping is *defined*.

Best regards,
Tony.
