- Editors
-
- One of the tools that you will probably use quite a lot on
- this system is the editor. You will probably use an editor, most
- often, to type in messages to be sent to others. As you become more
- advanced, you will use editors for other things. For instance, the
- people who keep this machine running use editors to edit programs that
- run on this machine. In fact, these help files were created using an
- editor on this machine.
- Editors can be very simple, or very complex. The three main
- editors that are provided on this system are pico, joe, and emacs.
- Pico is fairly easy to use. It provides a list of keys on the bottom
- of the screen, and is not at all complex. If you use the "Pine" mail
- reader, you may notice that the default message editor is very much
- like Pico. Joe is also quite simple. It has good on-screen help. If
- you use Wordstar on a PC, you'll find Joe to be quite familiar.
- Emacs is slightly more difficult to use, but is VERY powerful,
- and is used by many experienced users. Emacs is available on nearly
- any Unix system, and is probably the most popular editor for Unix. If
- you're interested in Emacs, go ahead and run it, then hit Esc, the
- question mark, and the letter "t". This will start the Emacs
- tutorial, which will guide you through many of the basic functions of
- Emacs editing. If you need help at any point, just hit Esc, then the
- question mark (this starts the help system), then "a" for apropos,
- which will let you enter a string to search for. Emacs will then give
- you a list of commands that match your string. Keep an eye on the
- bottom line of the screen, as this is where Emacs displays informative
- messages.

- Viewers
-
- The two viewers, or "pagers", on this system are "more" and
- "less". They are both very similar, and which one you use is really a
- matter of preference. Advanced users will find a few functions in
- less that are lacking in more (a little backwards, considering the
- names, don't you think?).
- In either case, simply type "more file" or "less file" to view
- a file. Both viewers will give you a prompt after each page of
- information. At this prompt, hit the return key to display the next
- line, or the space bar to display the next page. Also at this prompt,
- hit "h" to display information on the available functions in the
- pager.
