24-3.1 Display Screens
The three main windows, or cursor zones,
are accessed through a cluster of three
CURSOR ZONE keys at the top center of
the unit. The location where the cursor rests
within each zone is called a cursor field. To
control the unit and enter data, all operator
inputs are made at highlighted cursor fields

softkeys, with customized on-screen labels,
interact with the screen to provide a unique

unrelated controls to find the one that is
needed.
