-The \emph{selection start time}, \emph{selection length}, and \emph{selection end time} display the current selected timeline values.
-The \emph{alpha slider} allows for varying the alpha value when using colors on the tracks as set in your appearance preferences for Autocolor assets.
+\emph{Automation type} is used for selecting one of the following: Audio Fade, Video Fade, Zoom, Speed, X, or Y (X and Y are for the compositor's Camera and Projector). When an auto line is present on
+the timeline and is being manipulated, a small square the same color as the line will be shown to
+the left of the Automation type. This is just an indicator to make it easy to see what is being worked.
+
+The \emph{curve zoom} affects the curves for the selected \emph{automation type} in all the tracks of that type and determines the value range for those curves.
+Use the tumbler arrows to the left of the numbers for the minimum value and the tumblers to the right for the maximum value, or manually enter the values in the text box.
+Good default values for audio fade are -40.0 to 6.0 and for video fade are 0.0 to 100.0.
+The tumbler arrows change curve amplitude, but the only way to curve offset is to use the fit curves button on the curve itself.
+
+The \emph{selection start time}, \emph{selection length}, and \emph{selection end time} display the current selected timeline values. When there is no selection, both the start and end time are the current
+position of the timeline and the selection length is 0.
+The \emph{alpha slider} allows for varying the alpha value when using colors on the tracks as set in your \texttt{Preferences $\rightarrow$ Appearance} for \texttt{Autocolor assets}.
