-# Basic use of capslock as a dual function key:
-#
-# - when 'capslock' is tapped (pressed + released), it behaves as ESC key
-#
-# - when 'capslock' is held, and used in combination with another key, it
-#   behaves like a 'ctrl' key modifier (just like xcape)
+# Usage: Place this file /etc/keyd/default.conf
+
+# Causes `capslock` to behave as `control` when pressed
+# and escape when tapped. Note that `control` is what
+# keyd regards as a 'modifier layer'.
+# See the man page for more details.
