The "Rubberbands" are a common way to implement "Object curve
effects".

You can place little boxes on the rubberband that act as handles for
your manipulation of the aspect of the effect the rubberband controls.
You would normally have zoomed in on your time line if you are
trying to use this method of control. You can have as many "handles"
as you wish/need to provide control of the effect/object.

The horizontal position of the handle defines a point in time on
the timeline. The vertical position of the handle defines the
amount of application of the effect, from 0 effect at the bottom
of the track/frame to maximum effect at the top of the track/frame.
( You can often specify the range for the effect when selecting it
as an Object curve.)

These Object curves are used for many functions besides what
we would normally call effects, like audio volume and the size
and position of an overlay.

The rubberbands are a quick and effective way to apply some
control, when exact numeric control isn't required.

Luck;
Ken
