Use the following commands to create bookmarks and access bookmarks from within Emacs.

Let us say that you are editing a file called foobar.org and suppose that you visit this file frequently to edit / view contents.

It would be convenient to access this file with couple of key strokes rather than navigate through the file structure (Dired) and visit the file.

Steps:

1. Open foobar.org for once by navigating to the file (visit the file in Emacs lingo)
2. While the file is open type C-xrm this will prompt you to provide the bookmark name for the file. Let us say foobar in this case.
3. Close the file (C-xk - kill buffer) - save if required
4. Now to visit the file, just type C-xrl - this will populate a list which will contain foobar.
5. Select foobar and hit Enter key
6. Use M-xbookmark-delete to delete any unnecessary bookmark of a file.

Note: Deleting a bookmark is analogous to deleting a shortcut in your Windows desktop.
The main file will be safe in its location and only the listing of the file from the bookmark menu will be removed.
