Little woman, say, extremely upset over minute gaming accessory (8)

I believe the answer is:

joystick

I'm a little stuck... Click here to teach me more about this clue!

'gaming accessory' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'little woman say extremely upset over minute' is the wordplay.
'little woman' becomes 'Jo' (character from Little Women).
'extremely' suggests removing the centre (only the extremes of the word are used).
'upset over' is a reversal indicator (knocked over).
'minute' becomes 'tick' (I've seen this before).
'say' with its middle taken out is 'sy'.
'sy' reversed gives 'ys'.
'jo'+'ys'+'tick'='JOYSTICK'

Can you help me to learn more?

(Other definitions for joystick that I've seen before include "Flight control lever" , "girl's to click" , "Pilot's manual control" , "Manual computer game gadget" , "Aircraft's control lever" .)

I've seen this clue in The Telegraph.
