+** COMMENT bind-map
+
+there is a package available in nongnu elpa that offers a macro that
+sort of generalizes the leader key idea. it also hooks into the evil package
+a bit to allow definition of bindings over different "states" that your
+editor might be in, like command or insert mode in xah-fly-keys. its fairly
+geared toward evil in that way, so i'm not sure how it will interact, but let us
+find out. the other option would be to make a simple macro of our own to hook
+into leader key maps.
