I have a few questions about TextEdit:

1.  TERec has two hooks for the programmer to put in his/her own text 
highlight routine.  I suppose the same routine will be called to 
unhighlight text as well.  Am I correct?

2.  How do I get TextEdit to overwrite the character at the cursor
position when I call TEKey, instead of inserting before the character?
My current solution is to use TESetSelect to select the character at
the cursor (actually the character in front of the cursor) so that
when I call TEKey the character is replaced.  This produce the undesired
effect of highlighting the character, which I circumvent by putting in
a highlight routine that does nothing in TERec.

This seems clumsy, is there a better way to do it?


Actually, I am writing a terminal emulation program; will I be better off
not using TextEdit?  Are there alternative TextEdit-type packages that
will help solve my problem?

Many thanks in advance.
