How do I detect scene changes in Adobe Premiere? I have a single clip with multiple edits in it. Is there an easy, automatic way to detect these? Ideally I'd just like them labelled in some way with support for "jump to the next label".

I realise it won't be 100% reliable since it would need to detect scene changes automatically, but perhaps there's something that can considerably speed up the process of splitting such a clip into separate scenes?
This isn't part of Premiere, but Scenalyzer is an external tool for this that I've had some good luck with.  It can scan a large video file and split it into smaller ones based on frame change detection.  Then you can work with the smaller files much more easily.  There's a freeware version, and a more featured paid edition.
