Martin,
Thanks for your suggestion. It did not work for me - reporting:

Type	Function: error in function handler
Object	edtText
Line	put Lookupchar(char beforecharpos of me) into newbeforechar
Hint	Lookupchar

The object field is "edtText" but if I change me to edtText
that throws up an error too. I am new to Rev and this kind
of scripting. Am awaiting delivery of Dans book in three weeks!

To explain a little more why the cursor position is important...
User entering text can be dealt with as keyDown.
But if User goes back and inserts cursor in an existing word,
I need to know what is either side so that those characters can
be matched against a list and replaced if necessary.

Hope that clarifies?
Thanks for your help,
Adrian
