The Alt and Ctrl keys
The left Alt key performs certain functions in conjunction with
other keys. The application program determines these functions.
In order to enter a combination of keys that include the Alt key,
hold the Alt key down while pressing the other key. The right Alt
key operates in a similar way but selects certain special charac-
ters. The Ctrl key, like the Alt key, carries out program functions.
Useful key combinations (software-dependent):
