SPF provides an interesting model for a screen based
editor.  A version for PC's is available from Command
Technology and I beleive there are some Unix versions
available.

It gives a busy screen with line numbers with several
modes.  Commands can be entered on the command line or
line oriented commands can be entered over the line 
numbers.  The normal mode is typeover with an insert
mode available.  The function keys are used for scrolling
on line help, and exiting.  On the PC the scrolling keys
on the numeric keypad are functional.

There may be some performance problems with low baud rates,
because of the necessity to repaint the screen.  Also,
sophisticated searching is not available.
