Pressing the Ctrl key prevents the SystemKey event from firing when the Alt key is pressed.
This example displays the name of the key that was pressed with the Alt key:
string ls_key
CHOOSE CASE key
CASE KeyF1!
ls_key = "F1"
CASE KeyA!
ls_key = "A"
CASE KeyF2!
ls_key = "F2"
END CHOOSE
This example causes a beep if the user presses Alt+Shift+F1.
IF keyflags = 1 THEN
IF key = KeyF1 THEN
Beep(1)
END IF
END IF
