Can anybody tell me how to do it?

Hi ecctao, welcome to the forum.

At this point there is no support for google toolbar in chrome. I am sure Google is working on it so they would integrate it in near future for sure.

In the meanwhile, what you can do is..use some bookmarklets for chrome with webmaster features.. YOu can see that here :
Google Toolbar for Chrome

thanks.
