There you go.  The "really good" analog scopes have a feature
where you can wait through part of the triggered waveform and
then fire off the second trace running at a faster sweep
to "expand" the view of a piece of the upper trace.  While
the second trace is running it highlights that portion of
the upper trace.

Thus the name "delayed sweep".  Now being done digitally
and all that, and called "zoom".  But you wouldn't know
unless you'd seen one before.
