sibelius 6-Creating crossed beams on two staffs of music?

I write a lot of music using multiple staves and was wondering how I could create crossed beams in sibelius 6? I've attached an image of what im talking about.

iirc you highlight the notes you want to move and then press something like ctrl+shift+down/up depending on which way you want them to go.

and it's command-shift if you're on a mac :)

Thanks for the help, that did the trick. (and that also just made my music look much neater and easier to read)
