i would suggest rob pike's paper on the sam editor.  sam is a
modeless, bitmapped mouse based editor with a very sophisticated
command language.  the paper is

	%A Rob Pike
	%T The Text Editor Sam
	%J Software -- Practice and Experience
	%V 17
	%N 11
	%D November 1987
	%P 813-845

the paper is both an explanation of how to use sam
and a description of the implementation.

sam (source) is available from the at&t toolchest.
i believe that the most recent version will run on
5620s, 630s, suns, or X windows.  (it can be run on
a dumb terminal or from a shell script with only the
command language).
