PressButton method
Causes the button object to behave as if the primary mouse button is pressed on the button object. When an ME display is migrated to an SE display, ME Key Assignments are automatically converted to SE Display Key definitions using this method with the Invoke command.
TIP:
You will have to define another Display Key that uses the Invoke command to call the ReleaseButton method after calling this method (otherwise the button will get stuck in the pressed position).
