Activate URLs and e-mail addresses in the current buffer.
You can make Emacs mark out URLs specially in the current buffer, by typing
M-x goto-address-mode. When this buffer-local minor mode is enabled, it finds all the URLs in the buffer, highlights them, and turns them into clickable buttons. You can follow the URL by typing
C-c RET (
goto-address-at-point) while point is on its text; or by clicking with
mouse-2, or by clicking
mouse-1 quickly (see Mouse References). Following a URL is done by calling
browse-url as a subroutine (see Browse-URL).
It can be useful to add
goto-address-mode to mode hooks and hooks for displaying an incoming message (e.g.,
rmail-show-message-hook for Rmail). This is not needed for Gnus or MH-E, which have similar features of their own.
