+# this lets a new monitor called "scratchpad" appear in from the top into the
+# current monitor. There the "scratchpad" will be shown (it will be created if
+# it doesn't exist yet). If the monitor already exists it is scrolled out of
+# the screen and removed again.
+#
+# Warning: this uses much resources because herbstclient is forked for each
+# animation step.
