It may be useful to create a default keyframe which has specific desirable values for later use. To do this, set the timeline to position 0 and be sure to disable \textit{generate keyframes while tweaking}. This will create a default keyframe at the beginning of the timeline which contains global parameters for the entire duration. Or if you have copied a non-default keyframe via Keyframes pulldown \textit{copy default keyframe}, it can be stored as the default keyframe by calling \texttt{keyframes $\rightarrow$ paste default keyframe}. After using paste default keyframe to convert a non-default keyframe into a default keyframe, you will not see the value of the default keyframe reflected until all the non-default keyframes are removed.
-The \texttt{keyframes $\rightarrow$ copy default keyframe} and \texttt{keyframes} $\rightarrow$ \texttt{paste} \texttt{default keyframe} allow conversion of the default keyframe to a non-default keyframe.
+The \texttt{keyframes $\rightarrow$ copy default keyframe} and \\
+\texttt{keyframes $\rightarrow$ paste default keyframe} allow conversion of the default key-frame to a non-default keyframe.
\texttt{Keyframes $\rightarrow$ copy default keyframe} copies the default keyframe to the clipboard, no matter what region of the timeline is selected.
The \texttt{keyframes $\rightarrow$ paste} \texttt{keyframes} function may then be used to paste the clipboard as a non-default keyframe.
And there is an easy way to delete keyframes besides selecting a region and using \texttt{keyframes $\rightarrow$ clear keyframes}. Click-drag a keyframe before its preceding keyframe or after its following keyframe on the track. This is the only way you can simultaneously delete keyframes on ganged tracks.

-When you create a drag selection and you modify a value in a plugin then everything in the selection gets modified the same. It use the previous keyframe and if there is no previous keyframe, then the default keyframe in your \texttt{\$HOME/.bcast5} definitions is used.
+\textit{Allow keyframe spanning} is enabled on the timeline by clicking on the icon that
+is on the right side of the \textit{Generate keyframes while tweaking}. With this enabled,
