Checked in.

There isn't one, as far as I know.

However, the "tree-select-row" signal on a GtkCTree is emitted when a
row is selected, and the callback for that signal can keep track of
information about the currently selected row.

In fact, it does that in Ethereal; in "create_main_window()" we have:

  gtk_signal_connect(GTK_OBJECT(tree_view), "tree-select-row",
    GTK_SIGNAL_FUNC(tree_view_select_row_cb), NULL);

"tree_view_select_row_cb()" could keep track of the currently selected
row, and the callback for key-press-event could use that.

We do the same for additional packet windows; this means we'd have to
keep track of *multiple* selected rows in *different* CTree widgets if
we did that.  It may be easier to do this the way we are doing it now.
