Using The Trackball
Use the trackball to select icons, windows, and menu items in the desktop. (Use
the keyboard to select menu items in the STANDARD USER INTERFACE.)
Position the pointer on the screen by rolling the trackball with your thumb. Select
an application or menu item by "clicking" the leftmost trackball button (Button #1).
In some applications, clicking the rightmost trackball button (Button #3) is required
to perform certain operations. Unless otherwise noted in this manual, always click
with the leftmost button.
With practice, you will learn to precisely position the pointer on the screen using the
trackball. You should also practice "clicking" and "double-clicking" the leftmost
button.
A single click of Button #1 with the trackball pointer on an icon or window will make
that item "active". That is, it will be the currently-selected icon or window in the
desktop. (It will appear highlighted.) A double-click of Button #1, performed
quickly, will "open" (start) an application or select a parameter.
When an icon or parameter has been selected, the pointer changes shape to
indicate that you must wait a few seconds. If the pointer doesn't change
shape, double-click again until it does. Do not double-click the trackball
button again if the pointer has already changed shape. This will open two
identical windows.
