QuickShift for Google Chrome is a must-have extension for dual monitor setups
What does QuickShift do? It allows you to move your current tab to a different Chrome using a hotkey combination: Ctrl+Alt+Right/Left arrow . Often, when I'm writing, I need to pop a source article over to my secondary monitor, and this is an incredibly elegant way to do it.
QuickShift also adds Windows 7-style tab switching. In the same way that you can tap Win+[a number] to launch or switch to an application on your taskbar, QuickShift allows you to change tabs in Chrome by pressing Ctrl+Alt+[1-9]. Like most Google Chrome extensions that interact with your tab, you'll need to reload any active tabs before you can utilize QuickShift.
