So, the other day I was looking to put together a menu with items from a list in my controller and have the act of selecting an item correspond to a controller method call.  I eventually googled enough to find `radiomenuitem` and wound up using that.  But before I found out about `radiomenuitem` I saw `listmenu` and tried to make that work.  I tried putting it under a `menu` item in a `menubar` but couldn't figure out how to make that work.  It either never showed up or it showed up underneath some other menu.  Obviously I don't know how to use the `listmenu`.  What is the typical use for one of these things?
