camelcasemotion (http://www.vim.org/scripts/script.php?script_id=1905)
This script defines motions ',w', ',b' and ',e' (similar to 'w', 'b', 'e'),
which do not move word-wise (forward/backward), but Camel-wise; i.e. to
word
boundaries and uppercase letters. The motions also work on underscore
notation,
where words are delimited by underscore ('_') characters
