I really dig the forward and back buttons for jumping around networks. I would really dig it if there was a back and forward navigation for the currently selected nodes.

So I started crawling through the preferences and I see /Houdini/Panes/Geometry Viewers/Move to First Operation is bound to Home key. I wanted to test it out but it doesn't do anything for me. Neither does the End key. I'm not sure this is the keyboard shortcut I'm looking for anyway…

Does anyone know if there a hotkey for pushing and popping the selected node?
