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 4X faster and 5X slower.
+Another example of user modifiable settings involving the plugins menu in the Resources window, can be found in \nameref{sub:expanders_plugin_subtrees}.
