@b<This window will tell you about what you can do with the View Tree part of the ASSIST.>

The @b<View Tree> side of ASSIST provides the user with a graphical
interface to IRAF packages and tasks, and to host programs that use
the IRAF-compatible parameter interface.  The initial @b<View Tree>
display is a hierarchical tree containing a leaf for the IRAF hierarchy
tree, and displays of helpful tasks, user-specified tasks, and
user-specified programs.

Clicking the @b<left> mouse button on the IRAF tree will display its
contents as a separate sub-tree of sub-packages and/or tasks.  If
the @b<left> mouse button is clicked on a task or program, 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.
