WebDriver has the concept of the "current context". This is normally the
"default content", which is essentially the top-level DOM. Operations are
typically assumed to apply only that context. For example, although a
window may contain many nested frames, "find element" will only find those
elements that match the criteria in the DOM of the current context.

Sections 7.2 and 7.3 attempt to describe how to switch that context into
either other windows or sub-DOMs. Put another way, webdriver can find and
interact with elements in DOMs other than the top-level DOM provided the
user has first switched to that context.

Does that help clarify things?
