+"
+" Usage: Start the script with the mapped key you'll be presented
+" with a prompt with the word under the cursor, press enter
+" to accept the word or type '\c' without the quotes to do a
+" case insensitive word or type in new word/expression to
+" search instead of current word.
+"
+" Once the search is complete a new window appears with the
+" matches found moving around the window will also update the
+" position of the current document.
+"
+" The following keys are mapped to the results window:
+"
+" q - Quit, and restore original cursor position.
+"
+" e - Exit, and keep results window open note that
+" movements on the result window will no longer be
+" updated.
+"
+" <cr> - Quit and place the cursor on the selected line.
