HowTo: Quickly test a webpage in different Internet Explorer versions

I just noticed that on Internet Explorer 11 developer tools console (appears when you press F12 key), there is a drop-down where you can select the rendering engine used. Edge means the very latest (IE11 one in this case) and you can select back to version 5.

Interestingly, there is no version 6 in the dropdown, don’t remember if there was an IE6 or if they jumped from IE5.5 or something to IE7 directly.
