Use Alt + <num> key to switch between google accounts for various google apps like Gmail, Play music, Google Drive etc
This extension is for people using multiple Google accounts in their browser. It often becomes a hassle switching between the different accounts for various Google apps like Gmail, Google Docs, Google Play Music, Google Drive, Classroom, Meet etc. This extension gives you the ability to switch across accounts seamlessly using keyboard shortcuts in Chrome.
So the extension makes use of that numbering.

To switch to say account number 2, you have to press Alt + 2 once you have already opened any of the supported google apps mentioned above.

Say you have gmail account 0 open, you can press Alt+2 to open the gmail account associated with account 2
