To facilitate quick access of Vim help for elements of a Vim script, eclim provides the command :VimDoc. When executed it will open the help docs for the supplied argument or for the element under the cursor. When mapped to a key binding of your choosing, this command can save you some repetitive typing and provides an internal map of some keywords to their help topic, which are not always as straight forward as :help word.
Note
If you come across any instances where this command does not find the expected Vim help topic, please report it so that it may be accounted for in future revisions.
