 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.

 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.
