scrubbing through revisions of a file

[Harvey Chapman]

Does anyone know if the following exists (gui or console)?

I'd like to look at a file in a blame/diff mode and have the ability to quickly skip backwards/forwards through the history of the file. Usually, I'm looking for code that used to be in a file and was removed later. I guess I could use bisect to find the rev, but there've been several times when I knew a bug was in a file (that I didn't write) and I wanted to quickly look through (in a pretty way) the changes that had been made to that file.

Thanks,
Harvey
