I can see where it's possible to Insert Time and push everything on the timeline after the playhead back. However, I need to delete time on the timeline and make everything after the playhead move forward. 
I'm hoping this is true since this is a non-linear editor.  I have so many cuts, splices, etc. that it would be impossible to select everything after the playhead (unless I could click and drag) ... Select All won't work because there's too many things (cuts, splices, etc.)  (unless I could click and drag).
