+// Package mapkeys provides a widget that can map one keypress to a sequence of
+// keypresses. If the user pnovides as input a key that is mapped, the sequence of
+// resulting keypresses is played to the subwidget before control returns. If the key is
+// not mapped, it is passed through as normal. I'm going to use this to provide a vim-like
+// macro feature in termshark.
