+Control Clear
+=============
+
+Description
+-----------
+Adds an additional configuration parameter, controlkeyclear. When set to 1,
+slock will no longer change to the failure color if a control key is pressed
+while the buffer is empty. This is useful if, for example, you wake your
+monitor up by pressing a control key and don't want to spoil the detection of
+failed unlocking attempts.
