Remove this key? (6)
I believe the answer is:
delete
I believe this is a double definition.
'remove' is the first definition.
(I know that delete is a more specific form of the action take away)
'this key?' is the second definition.
(key on a computer keyboard)
(Other definitions for delete that I've seen before include "Blot out or erase" , "'Cancel, cut (6)'" , "'Erase, remove (6)'" , "Remove or erase (text)" , "Strikeout, remove" .)
