ActionKey enumeration
Valid values of this enumeration are Enter and Pf1, Pf2, and so on through Pf24. The value that is set initially is Enter.
Usage notes
- You can use the ActionKey class ToNumber method to convert ActionKey enumeration values to a numeric value: the integer that remains after the key name is stripped of its "PF" prefix. For Enter, the numeric value is 0. These values are useful in a value-testing loop in conjunction with the User Language Jump statement.
