Usually this works by invoking a web +browser, but you can, for instance, invoke @code{compose-mail} from +@samp{mailto:} URLs. Packages such as Gnus may make active links from +URLs themselves. Otherwise you can use @kbd{M-x browse-url} to follow a +link, defaulting to the URL at point. Other commands are available +which you might like to bind to keys, such as @code{browse-url-at-point} +and @code{browse-url-at-mouse}. + +You can customize Browse-URL's behaviour via various options in the +@samp{browse-url} Customize group, particularly +@code{browse-url-browser-function}. You can invoke actions dependent on +the type of URL by defining @code{browse-url-browser-function} as an +association list.
