How to change SharePoint 2010 project deployment URL

I am currently developing some custom web parts using visual studio 2010 for my SharePoint 2010 project. I have deployed the web parts by giving by local site url. Then i try to change that URL to another site collection.

Solution for that one is

1.Simple select the project.


2.Now select Properties window near solution explorer.(But Dont right click on project and select properties)
It will open with options like Active Deployment configuration, Assembly deployment Target, Project File, Sandboxed solution, Site URL.

Simply change Site URL with where u want to deploy this webpart.
