ffap

Command `find-file-at-point' replaces `find-file'.  With a prefix,
it behaves exactly like find-file.  Without a prefix, it first
tries to guess a default file or URL from the text around the point
(`ffap-require-prefix' swaps these behaviors).  This is useful for
following references in situations such as mail or news buffers,
README's, MANIFEST's, and so on.  Submit bugs or suggestions with
`M-x report-emacs-bug'.

For the default installation, add this line to your init file:

(ffap-bindings)                      ; do default key bindings

ffap-bindings makes the following global key bindings:

C-x C-f		find-file-at-point (abbreviated as ffap)
C-x C-r		ffap-read-only
C-x C-v		ffap-alternate-file

C-x d		dired-at-point
C-x C-d		ffap-list-directory

C-x 4 f		ffap-other-window
C-x 4 r		ffap-read-only-other-window
C-x 4 d		ffap-dired-other-window

C-x 5 f		ffap-other-frame
C-x 5 r		ffap-read-only-other-frame
C-x 5 d		ffap-dired-other-frame

C-x t f		ffap-other-tab

S-mouse-3     ffap-at-mouse
C-S-mouse-3   ffap-menu

ffap-bindings also adds hooks to make the following local bindings
in vm, gnus, and rmail:

M-l         ffap-next, or ffap-gnus-next in gnus (l == "link")
M-m         ffap-menu, or ffap-gnus-menu in gnus (m == "menu")

If you do not like these bindings, modify the variable
`ffap-bindings', or write your own.

If you use ange-ftp, it is best to load or autoload it before ffap.
If you use ff-paths, load it afterwards.  Try apropos `C-h a ffap
RET' to get a list of the many option variables.  In particular, if
ffap is slow, try these:

(setq ffap-alist nil)                ; faster, dumber prompting
(setq ffap-url-regexp nil)           ; disable URL features in ffap
(setq ffap-shell-prompt-regexp nil)  ; disable shell prompt stripping
(setq ffap-gopher-regexp nil)        ; disable gopher bookmark matching

ffap uses `browse-url' to fetch URLs.
Also, you can add `ffap-menu-rescan' to various hooks to fontify
the file and URL references within a buffer.
