 The user's default settings, preferences, and other helpful files are retained across sessions in a hidden file, called \texttt{.bcast5}, in the user’s \texttt{\$HOME} directory. Initially when \CGG{} is launched there is an empty project and there are program default settings, and from then on the \texttt{.bcast5} directory will contain the settings that were set when quitting.  If you need to revert to the default settings, delete the \texttt{.bcast5} directory contents and restart \CGG{}.  Or you may want to rename it temporarily if you think you might want it back later.
 Although the location defaults to \texttt{\$HOME/.bcast5}, you can use the \texttt{CIN\_CONFIG} variable to override this location.  For example:  \texttt{export CIN\_CONFIG=/tmp/.bcast5}  will use a temporary setup for testing purposes.  It is also useful for multiple users sharing the same home directory who would like to have different configuration/preferences settings data.  And if you are experiencing inexplicable errors or crashes in \CGG{}, they may be due to a problem with \texttt{.bcast5} in which case taking it out of the picture  can at least eliminate this as the cause. Another use case is if we want multiple installations of \CGG{}, for example one stable and one experimental, we can create the \texttt{.bcastX} folder externally and then set it as default with the option \textit{Index files go here} in \nameref{sub:index_file_section}.
 
-Several ways exist to change \CGG{}’s operational characteristics.  A lot of variations can be made to  settings and preferences by using the \textit{Settings} pulldown from the main window and choosing \textit{Preferences}.

+In addition, there are currently 2 settings that can only be manually changed in your \$Home/.bcast5/Cinelerra\_rc file and then done so by very careful editing.  These include FAST\_SPEED and SLOW\_SPEED which allow you to modify the default 2X speed of \textit{Fast forwward} and the .5X speed of the \#2 keypad for \textit{Slow speed forward play}.
+For example, adding the 2 lines FAST\_SPEED 4 and SLOW\_SPEED .2 to the end of the Cinelerra\_rc wile will result in playing at 4 times faster and  20\% slower.
