Direct Links to Multiple Google Accounts

I have a few different Google accounts that I use regularly. For Gmail, I mostly have it set up to send email from one inbox. However, there are times when I want to open up a specific inbox without having to open up the main account, click my address, and then click my other account. The same thing applies for multiple calendars, drive/docs, etc.

I set up some bookmarks to directly link to the accounts and here are the formats.

In all cases, you need to be signed in to each of your accounts. And the order you signed in matters. The number (0, 1, 2) corresponds to the order in which you signed in (starting at 0)

Here is the format of the URLs:

Gmail:
https://mail.google.com/mail/u/0 (or just https://mail.google.com)
https://mail.google.com/mail/u/1
https://mail.google.com/mail/u/2

Google Calendar:
https://www.google.com/calendar?tab=mc&authuser=0
https://www.google.com/calendar?tab=mc&authuser=1
https://www.google.com/calendar?tab=mc&authuser=2

Google Drive:
https://drive.google.com/?tab=mo&authuser=0
https://drive.google.com/?tab=mo&authuser=1
https://drive.google.com/?tab=mo&authuser=2
