emacs

emacs is another, larger editor that comes with most standard systems. It

has many features not found in other editors, not to mention a built in LISP

interpreter. Because of its many features, many of the emacs commands are

multiple control or escape sequences. Some of the more common are listed

below:

 X C

Exit emacs

 H T

Presents a Tutorial on emacs

 H I

Displays the GNU Info pages on emacs

 X S

Save the current buffer to a file

emacs can be used to edit several buffers at one time, and provides many

different  source  environments helpful to creation of source code. These areas

are far too broad to be covered in these few paragraphs. The Tutorial is highly

recommended as a good way to get to know the features of emacs. The info

pages will give other, useful information not found in the tutorials. Both of

these should be enough to give you a good feel for how this editor works, and

what it can provide.
