Re: Undo questions
I strongly agree with previous articles about the necessity of
undo for a screen editor.  My own prferences are for something like
the vi undo, except that 4u would mean "undo the last 4 changes"
instead of "nothing" ( I still haven't gotten vi to undo more
than one change dependably ). Vi's 9-level buffering is nice,
but 4-5 would be adequate, and I think that LIFO *is* a reasonable
way to handle multiple undo-s.

  Another highly useful feature for an editor is recognition of 
paragraphs (based on mm macros or user choice).  Sentence recognition
is nice, but usually line-based commands are adequate.  However,
( for large-document-editing, which my department does a lot of,
and which the word processing people do, ) the paragraph is almost
as much a basic text-object as the word is.
