.H 1 "The menu data base"

The two or three rows of buttons in the lower part of the main window
provide access to the menu data base.
Most functions are available in this data base.  Objects you
create interactively are added to it.
Documentation is integrated at three levels.
Moving the mouse over a button produces a brief description
above the button. Pressing the left or right mouse button while
the cursor is over a selection
usually displays a
more complete description of the selection in the information window.
Some selections have an associated help file. Clicking the right mouse
button will display this file in a new window.

The information window contents is frequently updated.
Usually any information that you might want to reference later is also
scrolled into the DSP++ command history. If you want to preserve something
in the information window that has not been scrolled 
use the `append information window to DSP++ history option' under the
`Data base' menu.

You can `peel off' lines of the help data base
menu to appear in a separate window. Hold the control key down and
select the menu with the left mouse button. If the selection is
a menu then that menu will appear in a separate window otherwise 
the menu that contains this selection will appear.
There are never more than three
rows of buttons displayed in the main window. If you go deeper 
only the top level and the deepest two levels will
be displayed. Database menus in a separate window
display as many levels as you select
up to the height of the screen.

A menu data base button
is selected when you release the left mouse button
(or type RETURN) with the cursor
positioned inside the button.
Buttons that execute commands are in boldface.
Other buttons select new menus.

Commands can be entered directly in the lower highlighted area of
the main window. Just click the mouse in this area and type the command.
First the visible commands will be searched and then the entire data base.
Menus selected in this way are `peeled off' into a separate window
if the selection is not 
among the displayed buttons.
Type the `escape' key to stop entering commands
and return input to pull down menu shortcut keys.
