Avoid key getting cut (6)
I believe the answer is:
eschew
'avoid' is the definition.
(eschewing is a kind of avoiding)
'key getting cut' is the wordplay.
'key' becomes 'esc' ('Escape' key on a computer keyboard).
'getting' is a charade indicator (letters next to each other).
'cut' becomes 'hew' (I've seen this before).
'esc'+'hew'='ESCHEW'
(Other definitions for eschew that I've seen before include "'Avoid, keep away from (6)'" , "'Stay clear of, shun (6)'" , "Ignore" , "'Avoid, shun (6)'" , "Avoid or abstain from, food or people" .)
