Typically stand in line with key (4)
I believe the answer is:
wait
'typically stand in line' is the definition.
(wait in line)
'with key' is the wordplay.
'with' becomes 'w' (abbreviation).
'key' becomes 'ait' (I've seen this in another clue).
'w'+'ait'='WAIT'
(Other definitions for wait that I've seen before include "Serve at table" , "Hang about" , "Stay" , "Hold on" , "Serve on tables" .)
