They are placeholders for content to be later inserted into.
Typically, I think, you would have actions called e.g. sidebarAction and
navAction. In each of these you would have a line like
$this->_helper->viewRenderer->setResponseSegment('sidebar');
You would then add these actions to the actionStack, so that on any request,
these two actions were called in addition to your main action.
Sorry that's a bit terse, but should help you get started.
