Arrow Keys - The arrow keys will accept the entered data and move the cursor to

an acceptable range for the field. The user must clear the error before proceed-

Restoring Valid Data - The user can clear and re-enter data from any field prior
to leaving the field. If the arrow key or the ENTER key is used to move off the

the field.
Selectable Fields
A selectable field gives the user a choice of inputs from which to toggle
through, and is recognized by the ">" cursor preceding it.

2. ENTER Key - cycles the user through the available selections.
3. Arrow Keys - move to the next field and accept the selection.

number.
4. Verify Cursor Type - Upon pressing the ENTER or DOWN ARROW
key, if the cursor moves across to the units column and changes to
the ">" selectable cursor, the user is in a suction pressure field which

Absolute Pressure Fields
This field is actually a combination of numerical and selectable fields. The

select vacuum or non-vacuum ranges.
