Apple Final Cut Pro 7 - Manual (Page 414)

Tip: If you are having a hard time dragging the markers out of the clip, try dragging
the markers to the Name column heading in the Browser. When you see the Name
column highlight with a rectangle, release the mouse button.
Subclips, identified by special subclip icons, are created. If you chose Modify > Make
Subclip, the markers remain in the clip after the subclips are created. If you dragged the
markers out of the clip, the markers in the clip are removed.
All of the material
between the markers
you selected should
now appear as subclips.
Tip: Subclips are named based on the marker name. To create more meaningful subclip
names, change the marker names in the Browser before creating subclips.
