If you are looking to have Alleva open on two screens for purposes of reviewing an older note while creating new documentation on a readmit. This will allow you to have that functionality. 

1. Looking at your Search Google or Type URL section (as seen below in the screenshot) you'll click the 3 dots to open up a Chrome Menu.

2. You see a New incognito window or when you are clicked on Google Chrome you can use the Hotkey Ctrl + Shift + N. And it will open a new window separate tab. Incognito will not be able to snap onto other non-incognito Google Chrome pages.

This will allow you to login into another Alleva account.
