-The Viewer and Compositor each have a timebar control area with an indicator line below the video
-output. The \textit{timebar} shows the whole time covered by the program. When a video asset
-is loaded in the main window and you move in the compositor, the insertion pointer in the main
-window will reflect those movements. However, this is not the case with the viewer. In the viewer
-only that specific media is shown and there is no corresponding movement on the timeline.
-
-Both the Compositor and Viewer support labels and in/out pointer which are displayed in the timebar.
-And as with the movements, when you use the labels or in/out pointer in the compositor timebar,
-the result will also be reflected in the main window timebar. Along with that, of course, when
-you move to a label or in/out pointer in the compositor, the insertion point in the program window
-will go to that position.
-
-The timebar in the compositor and the viewer can be used to define a region known as the \textit{preview region}.
-This preview region is the region of the timeline which the slider affects.
-By using a preview region inside the entire program and using the slider inside the preview region you can very precisely and relatively quickly seek in the compositor and viewer.
-The preview region can be especially handy when you have large pieces of media by previewing one section, then move to the next section.
-
-The active preview region is the zone between the edge bars.
-The full range of the window slider pointer action is down-scaled to the active preview region.
-To use this, set the preview active region as a media time region of interest.
-Now addressing the timebar with the mouse only operates as if the timebar is zoomed to the scale of the active preview zone.
-This has the effect of magnifying the interesting media in terms of the mouse pointer addressing, for fine-tuning.
