If you want more information than what is shown in the description, click a link to one of the related topic, or one of the search results appearing in the dynamic help section in the help view.
Depending on help preference settings, requesting context-sensitive help may display context help in an
infopop instead of help view. You can dismiss the infopop by clicking outside it, or by pressing
Esc.
If you want more information than what is shown in the infopop, click a link to the related information. This
opens the Help browser to the selected topic and closes the infopop. The list of related links stays in the left hand
frame, so you do not have to press F1 again if you are interested in other topics related to the same
widget.

following table shows how to put focus on some of the different kinds of widgets.

| List | Click an item in the list. |
| View or pane | Click the title bar of the View or pane. |
