 <lead>so  --  sort, case sensitive
 <lead>si  --  sort, case insensitive

These mappings work in visual and normal mode--in normal mode they take a motion operator.  See ":help mapleader"

Function:
 CharSort#Sort({string} [, {i/c}]) -- Sort {string}
    {i/c} == c  -- match case (default)
    {i/c} == i  -- ignore case
