Keypad Operation - Garmin GPS 100 Owner's Manual

The area of the page with light characters and dark background is called the
cursor. The cursor may be moved to locations on the page called fields. A
field is a group of characters treated as a single unit of information which allow
you to enter data. You will encounter four types of fields.
Numeric fields accept numbers. For example, you will enter the time in
an numeric field.
Alphanumeric fields accept numbers as well as letters. For example,
you will enter the date in an alphanumeric field.
Cyclic fields allow you to select from one of several available options.
For example, you may select between ETE (estimated time enroute) or
ETA (estimated time of arrival) using a cyclic field. Cyclic fields are
indicated on the display by a ">" character.
Confirmation fields allow you to indicate your acceptance or rejection.
For example, you will be asked to confirm the initial position, date, and
time before satellite acquisition begins. Confirmation fields always end
with a "?" character.
