+If you like to use different window layouts than the default for certain scenarios, you can setup, save, and load 4 options.
+First position your Cinelerra windows where you want them to be and then use the Window pulldown and choose \emph{Save layout}.
+To use the default name of Layout \#, when the popup comes up, just click the green checkmark OK on the Layout popup menu.
+If you would like a specific name for your layout so you can remember what it is for, keyin 1-8 english characters that are meaningful to you (english characters mean you can not use the German umlaut or the French accent).
+Legal characters are a-z, A-z, 0-9, \_ (the underscore character) and a limit of 8 total.
+If you keyin more than 8, only the last 8 characters will be used.
+To rename a currently existing layout, use the Save layout option again on the one to rename, and keyin a different name into the text box or blank for the default name (figure~\ref{fig:window_layouts}).

+The files containing the coordinates for your layouts will automatically be saved in the \texttt{\$HOME/.bcast} directory as \texttt{layout\#\_rc} or \texttt{layout\#\_8chars\_rc}.
+
+To use the desired layout, keyin the shortcut or use the Window pulldown and choose \emph{Load layout} and then make your choice.

+\subsection{Just Playing!}%
+\label{sub:just_playing_}
+What if you are just using Cinelerra to play media and listen to tunes?
+After loading your media, just hit the space bar to start playing and then again to stop playing.
+Other than that, use the transport buttons on the top bar of the Program window.
+Other ways, not previously mentioned to “play around” are described next.
+
+\subsubsection*{Repeat Play / Looping Method}%
+\label{ssub:repeat_play_looping_method}
+
+There are 2 methods for repeat play or looping on the timeline and 1 method for both the Compositor and the Viewer. This works in conjunction with any of the transport buttons or shortcuts in either forward or reverse as usual. The 1 exception is that the Shift button can not be used to either add or subtract audio within the repeat area.
+
+
+\emph{Shift-L on the Timeline}, repeats the selection per the algorithm outlined next.
+When setup, long green lines are displayed across the entire set of tracks which shows the start and end of the loop.
+\begin{enumerate}
+ \item Highlighted selection repeats loop and takes precedence over all other possibilities.
+ If the cursor is before the highlighted area, it will play up to the area and then repeat the highlighted section.
+ If the cursor is after the highlighted section, play will start at the beginning until you get to the
+ highlighted section and then repeat.
+ \item When both In and Out pointers are set, it repeats the section between [ and ].
+ \item If only one of the In or Out pointers is set, it loops the whole media.
+\end{enumerate}
+
+\emph{Ctrl+Shift+transport button on the Timeline, Viewer, and Compositor}
+
+\begin{enumerate}
+ \item Repeats entire media if no In or Out pointer set.
+ \item In and Out pointer set, repeats area between pointers.
+ \item Only In pointer set, repeats from In to end of media.
+\end{enumerate}
+
+\subsubsection*{Last Play Position Memory}%
+\label{ssub:last_play_position_memory}
+
+
+When you play media, the start/end playback positions are saved as if they had been made into temporary labels.
+They appear on the timeline as purple/yellow hairline markers representing the last start/end labels for the last playback.
+They can be addressed as if they are label markers using:
+
+\begin{description}
+ \item[Ctrl$\leftarrow$] tab to the label before the cursor, that is “play start”
+ \item[Ctrl$\rightarrow$] tab to the label after the cursor, that is “play stop”
+\end{description}
+
+
+You can use these markers for re-selection.
+Additionally, the selection region can be expanded by “pushing” the markers using single frame playback.
+Use frame reverse (keypad 4) to push the start play marker backward, or use frame forward (keypad 1) to push the end play marker forward.
+
+Another handy feature is to use the combination of Ctrl-shift-arrow (left or right) to select the media from the cursor position (red hairline) to the start or end marker by “tabbing” to the label markers.
+For example, tab to the beginning of the previous play region using Ctrl-left-arrow to move the cursor to the beginning of last play, then press Ctrl-Shift-right-arrow to tab to the end of the playback region.
+Now you can clip/play/expand or edit the previous playback selection.
+
+\begin{description}
+ \item[Ctrl SHIFT$\rightarrow$] tab cursor to label right of cursor position and expand selection
+ \item[Ctrl SHIFT$\leftarrow$] tab cursor to label left of cursor position and expand selection
+\end{description}
+
+
+\subsubsection*{Playback Speed Automation Support}%
+\label{ssub:playback_speed_automation_support}
+
+
+The speed automation causes the playback sampling rate to increase or decrease to a period controlled by the speed automation curve.
+This can make playback speed-up or slow-down according to the scaled sampling rate, as “time is multiplied by speed” (speed X unit\_rate).
+
