(require 'ncl-doc)
(add-hook 'ncl-mode-hook
(lambda ()

2) It tries to find a URL for the given string
+ if it finds URL for the string call the browser to open that URL
+ If no URL is found, then goes on to search for the given string.
+ Displays all search matches in separate buffer category wise. In that buffer RET in any search match will call browser for take you to that page.
+ If no matches found for a given string it leaves you there
