She swears audibly at something on computer screen (6)
I believe the answer is:
cursor
'screen' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cursor that I've seen before include "Location indicator on a screen" , "Device indicating position on computer screen" , "Indicator on computer screen marking position" , "Moving indicator on computer screen" , "blinking computer guide!" .)
