We all know that Microsoft has released first Platform Preview of the upcoming version of Internet Explorer i.e. IE10.
Did you know that IE10 platform preview allows you to switch between IE5, IE7, IE8, IE9 and IE10 rendering modes?
Microsoft has introduced a new feature in IE10 preview build which allows you to force the rendering mode using Debug menu. You can use this feature using following simple steps:
1. Open IE10 platform preview and click on Debug menu.
2. Now you can select any desired rendering mode. Its called Document mode in IE10. Select any "Force IE Document Mode" option.

3. You can also use keyboard shortcut ALT+5, 7, 8, 9 and 0 to force IE5, IE7, IE8, IE9 and IE10 document modes respectively.
4. To reset document mode, simply select "Reset Document Mode to page default" option or press CTRL+ALT+0 keys.
5. Whatever document mode you select, its shown in Status bar.
Really nice feature for users as well as website developers to test their websites in different IE versions.

Yes, I agree. Where is IE6? Or does it use the same rendering as IE7 or IE5?

yeah.funny that ie5 is there but not ie6 unless ms forgot to add it or it could be due to the fact that there were 2 versions of IE6.One for win 98se and the other for xp.

I'm about as big a fan of IE as I am of the bubonic plague :-), but I have to admit that this is a pretty good idea. If it works, businesses should no longer have any reason to fear upgrading their systems (Win7, at least) to IE10, as their in-house web apps should now work without interruption or expensive, time-consuming upgrades.

IE6 standard was replaced by IE7 standard according to Microsoft, thats why IE6 is not in the list.
