Go to Graphs (shortcut)
Shortcut like g c for Go to Code or g r for Go to Releases (Love this one) to jump into repository Insights tab
Example link: Go to insights from repo by hitting g h
In other words you want shortcut to the Insights tab?

more-dropdown hides the Insights tab into the More dropdown because considered of infrequent use. A shortcut would mean that it’s of frequent use, I think, therefore contradicting the existing feature.
Since there are only so many shortcuts available and risk of conflict is high, we generally don’t hide them unless deemed of frequent use.
