Primary Controls and Status Bar 2
An application’s primary controls go at the bottom of its main view,
usually on a status bar. A status bar is not strictly required, but it helps
to visually anchor the controls. Figure 2-10 shows sample status bars
with assorted controls.

Each application can have a different set of controls, but an application’s main
view must have a Close box unless the application is the backdrop (see “The
Backdrop” on page 2-29 and “Closing a Main View” on page 2-32). Close boxes
and other standard status-bar controls are described in “Close Boxes” on
page 3-14 and “Standard Newton Buttons” on page 3-22.
On an Apple MessagePad, the status bar is a black line two pixels thick,
with end points two pixels from the right and left edges of the application’s
main view.
Separator Bars 2
In a view that may display more than one variable-sized item at once, like
the notes in the Notepad, a separator bar heads each item. A separator bar
identifies the item below it and carries controls that apply only to that item.
Figure 2-11 shows some separator bars in the Notepad.
