Had nothing to do with key getting cut (8)
I believe the answer is:
eschewed
'had nothing to do with' is the definition.
(to eschew is to avoid or have nothing to do with)
'key getting cut' is the wordplay.
'key' becomes 'esc' ('Escape' key on a computer keyboard).
'getting' says to put letters next to each other.
'cut' becomes 'hewed' (I've seen this in another clue).
'esc'+'hewed'='ESCHEWED'
(Other definitions for eschewed that I've seen before include "left alone?" , "Shunned, kept away from" , "Deliberately avoided - chew seed (anag)" , "Shunned or avoided" , "Steered clear of" .)
