I zoom the camera in all the way to first person, lay down on the sofa, turn the sound effects all the way up, double click, glance at the screen if the mouse is not over the bobber recast, however 90% of the time with the oversized bobber and camera zoomed all the way in the mouse is over the bobber. I have a hand held wireless keyboard (used mostly for presentations etc.) which has a thumb driven mouse pad and right/left click buttons on it.
