Function Keys
Function keys, such as S1 and S2, permit the
terminal to perform certain functions or operations
with few keystrokes by the operator.
On keyboards that have a Ctrl (Control) key, the
S1 and S2 functions require a combination of two
keys:
1
Press and hold the Ctrl key.
2
Then, press the S1 or S2 key.
If no Ctrl key is present, you need only to press
the S1 or S2 key. Figure 2-4 illustrates the keys
on a typical keyboard.
Enhanced Alphanumeric Keyboard:
On the enhanced alphanumeric keyboard:
The ESC (Escape) key functions as S1.
The ENTER key functions as S2.
Manager’s Keylock
The keyboards can be equipped with a manager’s
keylock, for special override functions as
determined by your store procedures.
During normal operations, the keylock is in the
OFF position. When needed, it can be turned to
the ON position to enable special keying functions,
and then turned OFF again. The key cannot be
removed while it is in the ON position.
