you can use a touch sequence for this like:
var Test::TouchSequence seq = new Test::TouchSequence;
seq.Add( <220,150>, 2000 );
SendTouchSequence( seq );
This sequence contains only one touch event which simulate a press for 2000ms at <220,150> and than sends the release event.
With a touch sequence you could also simulate finger movement by adding further touch events at different positions.
