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

'slide around crabwise?' is the definition.
I can't judge whether this defines the answer.

'slide around' is the wordplay.
'around' indicates an anagram.
'slide' is an anagram of 'SIDLE'.

Can you help me to learn more?

(Other definitions for sidle that I've seen before include "Move along sideways" , "Walk furtively sideways" , "Walk stealthily" , "Make cautious progress" , "Slide (anag.)" .)

I've seen this clue in the Evening Standard.
