GitHub has introduced new hotkeys for navigating repositories and commit lists, aimed at enhancing the user experience for power users. These include shortcuts like @c@, @t@, and @p@ for accessing commits, trees, and parents, respectively, and @j@ and @k@ for navigating through commit lists, similar to Gmail and Vim functionalities. The updates, which are already popular among users like Chris Wanstrath, promise to streamline interactions and improve efficiency when working within repositories. Additionally, GitHub has plans to introduce more hotkeys and a cheat sheet to assist users, along with the upcoming release of per-project wikis.
