For Refresh, simply add a button with this code
FOr search, what exactly do you mean by search? Are you looking for a button which would execute a search of the net? Like from a search engine? IF so, I recommend you download the google toolbar from google.com. It has a search box on the toolbar at all times and a button to execute. If you put your cursor in the box and hit the button to open the osk, you can type in a search string.
