How do I delete some Google Chrome apps or attachments, I don't know what they're called?

So basically I downloaded some of these apps a while ago. The ones on Google Chrome. This one I have is really annoying because when ever I highlight something it brings up all these stupid options, and whenever I click CTRL+V to copy, it opens some stupid link on the page. Now whenever I click enter, it takes me to Google Maps. So where do I manage these apps, and be able to delete them?|||Try clicking spanner right from address line at the top of chrome -%26gt; then select Tools -%26gt; then select Extensions
