The Help System

The Pablo Help System provides a means of obtaining on-line assistance
about Pablo.  Help is available for all of Pablo's major features, and
the type of help provided depends on where help was requested.  

When a user requests help on a particular topic, a help dialog will
appear.  The top part of the dialog presents the topic name and the
help text for the selected topic.  The help text is in a window that can
be scrolled horizontally and vertically if the text is too long.  The
dialog may also be resized to make more of the help text visible.  

Below the current help text, there is a list of topics related to the
current topic.  These topics represent more detailed information that
the user may request help on.  The list of detailed topics may be
scrolled up or down until the desired topic is found.  Clicking the left
mouse button over a detail topic causes the help dialog to display that
topic's help text and detail information list.

Since the help system is arranged in a hierarchy, it is possible to go
up and down many levels of topics.  Clicking on a detail topic goes down
the hierarchy one level, and clicking on the the PREVIOUS button goes up
one level in the hierarchy.  The TOP button causes the help system to go
all the way back to the level where this help dialog started out.  Note
that it is not possible to go any higher than this point, nor is it
possible to have multiple help dialogs that have the same starting
point.  The OK button dismisses the help dialog.
