[AccessD] A2K: Go to end of field and add a Hard Return

Hello all 
I have a control on a form (based on a memo field in a table)
When it gets the focus I want the users cursor to go to the end of  whatever text is there 
then add a vbcrlf then that's here I want the user to start typing

Is this do-able?

Many thanks in advance

Darren
