One feature of Google Chrome I use frequently is to duplicate the tab. If I am reading an email but want to search my inbox without leaving the email I am reading, duplicating the tab allows me to be in my email twice. Sometimes when using a web 2.0 tool there are 2 things I want to be working on in the same tool. Duplicating the tab allows me to be two things at once and not have to drill back down to the same spot.
Right click on the Chrome tab to reveal a menu of options. Choose "Duplicate" to have the same website open twice.
