Make URL "clickable"?

[monnier]

AFAICT, when I have a URL in the Org buffer, it's treated like any other chunk of text rather than turning it into a hyperlink. Am I missing something?

Also, I can't see a way to copy some text (to paste it elsewhere, e.g. in a browser when that text is a URL). So I guess these are either two feature requests, or two cases of me being a bit dense.
