What we really need is a list object type so we can put stuff in the list
and allow the user to select items in the list without being able to change
the text of the list.  But we don't.

To solve this problem for in my own stacks, I set up a scrolling field with
locked text.  Next to each line in the field, I put a little arrow button.  If
the user clicks on the field, nothing will happen.  But if the user clicks
on the arrow, the script of the button will compute the line of the field
that this arrow is pointing to based on "the scroll of field such-and-such"
and then extract that line from the field.  If anyone is interested, I can
put up the script of the button that does this.
