The easiest way to use these backup files is to edit them, then save them to the original file name. This may be useful for placing tags at the beginning of certain sections of code in a program. Emacs will automatically save your bookmarks when you exit. You can then jump to a bookmark from this list by typing the letter o next to the desired bookmark name. Configuration Files You can create an .emacs configuration file in your home directory to accomplish customizations such as mapping function keys, entering emacs environment commands, and setting emacs variables.
Users can lock files during a revision cycle.
If another user visits a file that is locked, the user will receive a warning message. When revisions are complete, the lock can be removed. Emacs also enables you to keep a revision history on any file so you can track your modifications. Program Development emacs can be used as an integrated development tool.
