+--- Adapted very loosely from https://github.com/jasonrudolph/ControlEscape.spoon
+--- Removed timing/delay; always send Escape as well as Control
+---
+--- Make the `control` key more useful: If the `control` key is tapped, treat it
+--- as the `escape` key. If the `control` key is held down and used in
+--- combination with another key, then provide the normal `control` key
+--- behavior.
