keep a low profile
keep a stiff upper lip
keep about
keep abreast of
keep alive
keep at bay
keep away
keep back
keep count
keep from
keep hold of
keep house
keep in
keep in check
keep in mind
keep it up
keep mum
keep off
keep on
keep one's distance
keep one's head
keep one's head above water
keep one's mouth shut
keep one's promise
keep one's shirt on
