Full resolution stills of the playhead?

I'd like to grab some stills of some frames from a set of videos i've just imported into my newly brought FCPX. I wondered whether anyone knew of a way to do this. At the moment i've been trying to screengrab and enlarging the viewer as large as possible... feels a bit clumsy though.

Is this possible, any suggestions?

Thanks.

Found it... There is a Save Current Frame option under the share menu that does exactly what i wanted... sadly it doesn't work when skimming the event library, only the main storyline. Still, i can live with that.

Excellent.
