Some pages provide groups of parameters, which can be hidden or shown. To toggle
between hiding and showing a group, simply click the group title button that appears above
each group. The button appears with a down-pointing or up-pointing arrow, indicating that it
can be collapsed or expanded when clicked, respectively.

4.1.6.3 Modifying and Saving Parameters
When you modify a parameter value on a page, the Edit symbol appears to the right of
the parameter. This indicates that the parameter has been modified, but has yet to be
applied (submitted). After you apply your modifications, the symbol disappears.
