Enabling Control Keys for webtop

Can we have an option which will turn ON/OFF the following feature on need basis.
"User should be able to use Control Key freely with webtop as he would have been using with a desktop. There could be restrictions, but worth to try.Bascially if the option is ON, all control key operations should act on webtop."

The idea is for an end user to give full desktop kind of feel, he should feel like he is dedicated desktop when he is webtop.
