Drag any selected handle to the desired target staff. As you drag the single handle, all selected handles move simultaneously. You don’t need to drag the handles to any particular pitch on the new staff—simply release the mouse button when the cursor is directly on the target staff, and you’ll find that the notes have now moved to the new staff. Their beams and stems, however, still originate in the source staff.
If you have a relatively simple cross-staff notation, you’re done. If you need the beam in the middle, continue with the instructions below.
