 ganged the same so that they will remain synchronized.  However, if as recommended you have Settings of \textit{Align cursor on frames} set, video will always snap to a frame, whereas audio does not.  Because the smallest pieces are audio and not video, when video is present in order to maintain synchronization be sure to do the double click on the video track.  The single/double click feature also works in the same manner for Fade Automation.

 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.
