When you define the buttons like this...

  <input name="new" type="submit" value="New search" />
  <input name="start" type="submit" value="Start" />
  <input name="previous" type="submit" value="Previous" />
  <input name="next" type="submit" value="Next" />
  <input name="last" type="submit" value="Last" />

When the user selects one of the buttons, you should get an entry for
the field representing the button in the FieldStorage object. So, if
the user presses the "next" button, there should be an entry mapping
that name ("next") to some value ("Next" in the above example) in the
FieldStorage object.
