There’s a little script written for AutoHotkey that allows you to switch among Chrome tabs by simply holding mouse’s right button and scrolling its wheel up and down.

If you have the AutoHotkey installed you’ll need to use that script: http://www.codigobit.net/software/GCTabWheel.ahk. Or, if you don’t want to use AutoHotkey you cam run this executable file http://www.codigobit.net/software/GCTW.exe and you’re set to easy switch between the tabs you have open in Google Chrome.
