you can copy paste from one seq into another.
you can load a seq into the voiewer and edit from it.
it will cut into the new seq as a "nested sequnce"
which will look like one clip, but with a slightly different colour.
if you'd rather have the CONTENTS of the viewer sequnce,
that is, all your original cuts,
hold APPLE while you do the edit from the viewer.
you can also do this by holding APPLE,
then grabbing a sequnce from the browser,
and dragging it directly to the timeline
