I was thinking the same thing. Github has some useful keyboard shortcuts available: https://help.github.com/articles/using-keyboard-shortcuts/

I was going through searching for undocumented breaking changes (ie there were a lot) during the Angular2 alpha phase and stumbled on 'y'.

Click a line, press y, and it changes to the commit where that line was last changed. Since it shows the tag the commit applies to up top, it's relatively easy to mark what release was affected by a specific breaking change.
