@b<This window will tell you about the ASSIST tree displays.>

The ASSIST display consists of a number of graphical @b<trees>, called
graphers, arranged in a hierarchy.  Each @b<leaf> on a tree represents
a task, a program, a piece of documentation, or another branch of the
tree.  Pressing the @b<left> mouse button on one of the leaves will
activate it, resulting in the display of a task, a program, a
document, or another part of the tree.  You can traverse the trees
in the hierarchy to locate specific tasks or programs and then
activate these tasks and programs.

In the tree display, packages and sub-packages are always shown in
upper case with trailing ellipsis, while tasks are shown in lower
case. Documents are also in lower case, but have the word "doc" in
parenthesis placed after the name.

If the @b<left> mouse button is clicked on a task, a @b<parameter
editor> for that task is displayed.  This @b<parameter editor> can 
be used to edit parameters, run tasks, and obtain help.  If the
@b<middle> mouse button is clicked on a task, the help page for that
task is displayed.
