Return name of key that activated last screen read (Screen class)

The ActionKey read-only property returns an ActionKey enumeration which is the keyboard key that activated the last screen read.

Syntax

%key = screen:ActionKey

Syntax terms

%key A declared ActionKey enumeration (see below).
screen A reference to an instance of a Screen object.

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.
