presses the Alt key (alone or with another key).

Arguments

Argument	Description
key	KeyCode by value. A value of the KeyCode enumerated datatype indicating the key that was pressed, for example, KeyA! or KeyF1!.
keyflags	UnsignedLong by value (the modifier keys that were pressed with the key). The only modifier key is the Shift key.

Return Values

Usage

Pressing the Ctrl key prevents the SystemKey event from firing when
the Alt key is pressed.

Examples

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

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

IF keyflags = 1 THEN

IF key = KeyF1 THEN

Beep(1)

END IF
