More of which you can guess we tick at prime locations (3)
I believe the answer is:
etc
I'm afraid I can't even guess how this answer relates to the clue.

(Other definitions for etc that I've seen before include "And so on, in brief" , "And so on, briefly" , "And so forth (abbr)" , "'And the rest, in short (3)'" , "Etcetera (abbrev.)" .)
