+This is a very cool feature.  I haven't looked closely at this but can't\r
+this mechanism work the same as the other show-mode toggles, like crypto\r
+or indenting?  I wouldn't think it would require any more extra variable\r
+stuff than what is used for those other toggles.\r
+\r
+Also, the *really* sweet thing would be if the toggle actually cycled\r
+through display of the alternatives, only displaying one at a time.\r
+That would be very swank.\r
+\r
+David Edmondson put together the other show-mode toggling stuff, so he\r
+may be able to help with this as well.\r
