URLs (newbie question)

[Guldo K]

Hello.
I'd like to ask you two stupid questions :-)
I can't understand how can an url be inserted
in emacs; I mean a clickable one.
What's more, I'd like to be able to pass any
url I click on to a script I made, for opening
it with my browser. It's like:
$ ./url.sh www.whatever.com

Thanks,

Guldo
