editing the text of the buffer adjusts the beginning and end of each
overlay so that it stays with the text. When you create the overlay,
you can specify whether text inserted at the beginning should be
different kinds of terminals. It should be an alist whose elements
have the form @code{(@var{display} @var{atts})}. Each element's
@sc{car}, @var{display}, specifies a class of terminals. (The first

The button-creation functions all take the @code{&rest} argument
@var{properties}, which should be a sequence of @var{property value}
