bookmark-set is an interactive autoloaded compiled Lisp function in `
It is bound to C-x r m, <menu-bar> <edit> <bookmark> <set>.
(bookmark-set &optional NAME NO-OVERWRITE)
Set a bookmark named NAME at the current location.
If name is nil, then prompt the user.
With a prefix arg (non-nil NO-OVERWRITE), do not overwrite any
existing bookmark that has the same name as NAME, but instead push the
new bookmark onto the bookmark alist. The most recently set bookmark
with name NAME is thus the one in effect at any given time, but the
others are still there, should the user decide to delete the most
To yank words from the text of the buffer and use them as part of the
bookmark name, type C-w while setting a bookmark. Successive C-w's
yank successive words.
Typing C-u inserts (at the bookmark name prompt) the name of the last
bookmark used in the document where the new bookmark is being set;
this helps you use a single bookmark name to track progress through a
large document. If there is no prior bookmark for this document, then
C-u inserts an appropriate name based on the buffer or file.
Use M-x bookmark-delete to remove bookmarks (you give it a name and
it removes only the first instance of a bookmark with that name from
the list of bookmarks.)
