Value

t

Documentation

Controls when Emacs saves bookmarks to a file.

--> nil means never save bookmarks, except when bookmark-save is
    explicitly called (M-x bookmark-save (bookmark-save)).
--> t means save bookmarks when Emacs is killed.
--> Otherwise, it should be a number that is the frequency with which
    the bookmark list is saved (i.e.: the number of times which
    Emacs's bookmark list may be modified before it is automatically
    saved.). If it is a number, Emacs will also automatically save
    bookmarks when it is killed.

Therefore, the way to get it to save every time you make or delete a bookmark is to set this variable to 1 (or 0, which produces the same behavior.)

To specify the file in which to save them, modify the variable bookmark-default-file.
