Computer blinker (6)

I believe the answer is:

cursor

(Other definitions for cursor that I've seen before include "blinking computer guide!" , "that may appear on computer screen" , "Place-marker on screen" , "Indicator on a visual display" , "Location indicator on a screen" .)

I've seen this clue in the Universal.
