When you declare a form group that references a text form, the pfKeyEquate property specifies whether the keystroke that is registered when the user presses a high-numbered function key PFn (PF13 through PF24) is the same as the keystroke that is registered when the user presses the function key PF(n - 12).
If you accept the default value of YES for pfKeyEquate, logical expressions can reference only 12 of the function keys. For example, EGL sees PF2 as the same key as PF14.
Function keys on a PC keyboard are often "F" keys such as F1, but EGL uses the IBM® "PF" terminology so that F1 is called PF1.
