Use of the Keys
There are two types of keys:
run-time keys and editing keys. Run-
time
keys are used while running samples, for example, to start
and stop an analysis.
Editing keys are used to move through the
different displays and select program options. The ENTER key is
also considered an editing key. After you select an item by
marking it with the cursor, pressing ENTER accepts your
selection.
