Yes - that is actually stored as an attribute of the current node. You can see all of the attributes by adding
{$node|attribute(show,2)}
in your template, where node is your variable, and 2 is the number of levels of depth to go into the object arrays. Increasing it will give you more options, but may kill your server depending on how powerful it is (cause an error). The list can get long quick.
You can also steal code from the breadcrumb nav template in ezwebin to get this info (it uses a different method, using the path array).
