 Every page in a Sophie book has a master timeline which shows all the frames on the page. Each frame (or group of frames) has its own timeline as well.
+
+Currently, timelines can not be triggered by the book; they can only be demonstrated by opening the timeline interface and manually moving the playhead back and forth. Much more timeline functionality will be added in the future to Sophie.

+The channels show the activation of the different frames on the page. If a frame has been set to be invisible (so that portions of its channel turn yellow), the frame will be hidden when the page's playhead moves over that span in time. 
+
+== Changing visibility via the timeline interface ==
+
+To change visibility on the timeline, select a channel by clicking on it. Enter a start point and an end point for an interval of time (say 0:00-1:00). Then set the value to '''true''' (if you want the frame to be visible for that span of time) or '''false''' (if you want the frame to be invisible for that span of time). Then click the '''Set interval''' button. The change will be applied.
+
+Clicking the '''Set from''' button will change the visibility of the selected channel from the current position of the playhead to whatever the value is set to. Clicking the '''Set all''' button will change the visibility of the selected channel for the entire duration of the timeline.
