Emacs Concepts Emacs works with files and buffers . The file is just the usual UNIX file. The buffer is a temporary space in which you manipulate text. You can fill the buffer from a file and you can save the buffer to a file , which is the usual way that a file is edited. The emacs test.
C starts emacs with the contents of the file test.
If you don't include a file name, emacs starts with an empty buffer. Before you quit, you have to remember to tell emacs where to save the buffer. There are a zillion emacs commands, maybe more. On many systems, a keyboard which has arrow keys can be used for the previous, back, forward, and next commands. In emacs, key command sequences are so long that sometimes it is easiest to wipe the entire command and start over.
