You can't restrict using the Enter key without using VBA.
What you CAN do is place the field in a table cell and set the height of the
table row to EXACTLY a specific height. Then, they can still hit enter, but
they won't see anything...

Can you make the text form field not allow someone to press the enter key
and
start and new line and change the lines in the form.

When the text field is inserted, length changed to 15 characters and the
protect put on, you can tab to the field, type 15 characters and it will
stop, but when you press enter key it goes down and adds more lines??
