+Subject: [PATCH] Apply quickcancel
+
+Cancel slock by moving the mouse within a certain time-period after
+slock started. The time-period can be defined in seconds with the
+setting *timetocancel* in the config.h. This is useful if you forgot to
+disable `xautolock` during an activity that requires no input (e.g.
+reading text, watching video).
