Purpose: When you visit a file, point goes to the last place where it was when you previously visited the same file.

To use it, turn it on in the options menu - “Save place in files between Sessions”.

Alternatively, you could add the following to your InitFile:

(require 'saveplace)
(setq-default save-place t)

Note that using setq will not do because the variable is buffer-local.

Your saved places are written to the file stored in the file specified by save-place-file. This defaults to ~/.emacs-places. You may want to change it to keep your home directory uncluttered, for example:

(setq save-place-file "~/.emacs.d/saved-places")
