-returns a {\bf wxNode} pointer (or NULL if there are no more nodes). See the
-description for \helpref{wxNode}{wxnode}. The user will probably only wish to use the
-{\bf wxNode::Data} function to retrieve the data; the node may also be deleted.
+returns a {\bf wxHashTable::Node} pointer (or NULL if there are no more nodes).
+The return value is functionally equivalent to \textbf{wxNode} but might not be
+implemented as a \textbf{wxNode}. The user will probably only wish to use the
+\textbf{GetData} method to retrieve the data; the node may also be deleted.
