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

'play with' is the definition.

I cannot understand how the rest of the clue works.

(Other definitions for twiddle that I've seen before include "Jiggle" , "Twirl (thumbs?)" , "Finger idly" , "Play nervously (with something)" , "Turn in a purposeless way" .)

I've seen this clue in The Independent.
