Rather than retype the pathname each time you start Emacs, you could just jump to a bookmark you’ve named current project by having Emacs find the file and put the cursor wherever you set the bookmark.

Particularly if you are working on a project several directories down from your home directory or in a totally different filesystem, putting bookmarks in the file makes it easy to get back there. In Chapter 7, we’ll discuss how to find files on remote systems using ange-ftp mode. You can bookmark these files as well, getting back to your favorite FTP archives in one simple bookmark jump.
