Return a string that indicates the current mode. If [expr] is supplied and it evaluates to a non-zero Number or a non-empty String (|non-zero-arg|), then the full mode is returned, otherwise only the first letter is returned. Also see |state()|.

This is useful in the 'statusline' option or when used with |remote_expr()| In most other places it always returns "c" or "n". Note that in the future more modes and more specific modes may be added. It's better not to compare the whole string but only the leading character(s).

Also see |visualmode()|. Can also be used as a |method|: DoFull()->mode()
