Is there a way to long press ALT key .

Hi,

If you mean just Alt + TAB you can do that in the following manner:
type(Key.TAB, KeyModifier.ALT)

You can read more about that in key modifiers section:
http://doc.sikuli.org/keys.html#KeyModifier

Theoretically, there are "keyDown" and "keyUp" commands. More info here:
http://doc.sikuli.org/region.html#Region.keyDown
http://doc.sikuli.org/region.html#Region.keyUp

However, you should also notice that according to the documentation(first link), key modifiers should only be used in the modifiers parameter with functions like type(), rightClick(), etc. They should never be used with keyDown() or keyUp().

Cheers,
Eugene

  Screen s = new Screen ();
  s.KeyDown(Key.ALT);
