"CursorTrackerParameters"
• "CursorTrackerParameters" is an option for notebooks that determines details of the elliptical spot that appears when the cursor position jumps.
• This option is specified as a list consisting of pairs of numbers. Each pair is of the form {r, t} where r is the number of pixels in all directions by which the size of the cursor increases and t is the time in seconds that the cursor stays at that size. The list can contain any even number of elements.
• The default setting is "CursorTrackerParameters" 
{9,0.1,7,0.02,4,0.02,2,0.02}. This means that the cursor expands by 9 pixels in all directions for 0.1 seconds, then shrinks to 7 pixels for 0.2 seconds, 4 pixels for 0.02 seconds, and 2 pixels for 0.02 seconds before returning to its normal size. This sequence of changes gives the visual appearance of a flashing spot.
