checking whether a particular text exists::

        if Text("Do you want to proceed?").exists():

            click("Yes")

    ``Text`` also makes it possible to read plain text data from a web page. For

    example, suppose you have a table of people's email addresses. Then you

    can read John's email addresses as follows::

        Text(below="Email", to_right_of="John").value

    Similarly to ``below`` and ``to_right_of``, the keyword parameters ``above``

    and ``to_left_of`` can be used to search for texts above and to the left of

    other web elements.
