Laid back? Don't touch that... ! (4)
I believe the answer is:
dial
'laid back? don't touch that' is the definition.
'dial' can be an answer for 'laid back?' (I've seen this in another clue). I'm unsure of the rest of the definition.
'laid back?' is the wordplay.
'back?' shows that the letters should be reversed in order (I've seen 'back' mean this).
'laid' back-to-front is 'DIAL'.
Can you help me to learn more?
(Other definitions for dial that I've seen before include "Clock face" , "Laid up like clock-face" , "feature of old phone?" , "Ring the clock-face" , "Calibrated face" .)
