You can send key events directly to the client in order to have the mouse click at specific coordinates (and jump there).
eg.
ClientMouseEventHandler meh = getBot().getMouseEventHandler();
meh.generateBotMouseEvent(eventID, timeOfEvent, modifiers, x, y, clickCount, popupTrigger, buttonId, botEvent);
The class uses AWT events, so you can poke around the oracle AWT docs for more info on IDs and such.
