Audio Sound node - follow on

Following on from my previous post about audio:

In the Trax editor you can actually trim the sound directly. It's very hidden and there's no graphical hint at all, but if you LMB drag on the top left / right of the sound node, over the top time text, then you'll be able to trim the sound directly. If you're in the CamSequencer you can also, by doing a Shift MMB Drag, shift the audio itself within the sound track. All hidden features, but they work (only in 2011)
