Avoid getting key cut (6)
I believe the answer is:
eschew
'avoid' is the definition.
(eschewing is a kind of avoiding)
'key cut' is the wordplay.
'key' becomes 'esc' ('Escape' key on a computer keyboard).
'cut' becomes 'hew' (I've seen this before).
'esc'+'hew'='ESCHEW'
'getting' acts as a link.
(Other definitions for eschew that I've seen before include "give up" , "Avoid or abstain from, food or people" , "Avoid,shun" , "Ignore" , "Don't use" .)
