Bookmarks
=========

   "Bookmarks" are somewhat like registers in that they record
positions you can jump to.  Unlike registers, they have long names, and
they persist automatically from one Emacs session to the next.  The
prototypical use of bookmarks is to record "where you were reading" in
various files.

`C-x r m <RET>'
     Set the bookmark for the visited file, at point.

`C-x r m BOOKMARK <RET>'
     Set the bookmark named BOOKMARK at point (`bookmark-set').

`C-x r b BOOKMARK <RET>'
     Jump to the bookmark named BOOKMARK (`bookmark-jump').

`C-x r l'
     List all bookmarks (`list-bookmarks').

`M-x bookmark-save'
     Save all the current bookmark values in the default bookmark file.

   The prototypical use for bookmarks is to record one current position
in each of several files.  So the command `C-x r m', which sets a
bookmark, uses the visited file name as the default for the bookmark
name.  If you name each bookmark after the file it points to, then you
can conveniently revisit any of those files with `C-x r b', and move to
the position of the bookmark at the same time.

   To display a list of all your bookmarks in a separate buffer, type
`C-x r l' (`list-bookmarks').  If you switch to that buffer, you can
use it to edit your bookmark definitions or annotate the bookmarks.
Type `C-h m' in the bookmark buffer for more information about its
special editing commands.

   When you kill Emacs, Emacs offers to save your bookmark values in
your default bookmark file, `~/.emacs.bmk', if you have changed any
bookmark values.  You can also save the bookmarks at any time with the
`M-x bookmark-save' command.  The bookmark commands load your default
bookmark file automatically.  This saving and loading is how bookmarks
persist from one Emacs session to the next.

   If you set the variable `bookmark-save-flag' to 1, then each command
that sets a bookmark will also save your bookmarks; this way, you don't
lose any bookmark values even if Emacs crashes.  (The value, if a
number, says how many bookmark modifications should go by between
saving.)

   Bookmark position values are saved with surrounding context, so that
`bookmark-jump' can find the proper position even if the file is
modified slightly.  The variable `bookmark-search-size' says how many
characters of context to record on each side of the bookmark's position.

   Here are some additional commands for working with bookmarks:

`M-x bookmark-load <RET> FILENAME <RET>'
     Load a file named FILENAME that contains a list of bookmark
     values.  You can use this command, as well as `bookmark-write', to
     work with other files of bookmark values in addition to your
     default bookmark file.

`M-x bookmark-write <RET> FILENAME <RET>'
     Save all the current bookmark values in the file FILENAME.

`M-x bookmark-delete <RET> BOOKMARK <RET>'
     Delete the bookmark named BOOKMARK.

`M-x bookmark-insert-location <RET> BOOKMARK <RET>'
     Insert in the buffer the name of the file that bookmark BOOKMARK
     points to.

`M-x bookmark-insert <RET> BOOKMARK <RET>'
     Insert in the buffer the _contents_ of the file that bookmark
     BOOKMARK points to.
