Internet Explorer 9 lets users use the Ctrl + Tab combination on the keyboard to switch between tabs quickly. However, this feature will only let you switch tabs in a fixed position order. Many users may want to use the combination to switch tabs in the recent order, which is the way Alt + Tab acts. Fortunately, we can change this behavior easily.
I have never understand why cycling tabs using CTRL+TAB works differently that cycling open tasks using ALT+TAB. This tweak makes the user experience uniform between these two shortcuts.
1. Launch IE 9.
2. Click on the small gear icon on the top right of the program interface, and then go to Options.
3. In the Internet options window, go to the Advanced tab.
4. Scroll down to the middle of the Settings section, and put a check next to the Use most recent order when switching tabs with Ctrl + Tab option.
5. Finally, click OK to save the setting. You can try switching between tabs immediately to see the result. Later, if you decide to switch to the old behavior, just come back to the Advanced settings section and uncheck the above option.
