• ShowCursorTracker is an option for Cell which specifies whether an elliptical spot should appear momentarily to guide the eye if the cursor position jumps.
• The default setting is ShowCursorTracker -> True.
• Line breaking is normally set up so that small changes to expressions in input cells rarely cause large-scale reformatting; the cursor tracker appears whenever reformatting is required that makes the cursor position jump.
• The cursor tracker is intended to be sufficiently eye-catching to make the low-level human visual system cause an immediate shift in gaze.
• New in Version 4.
