roles

These are some bookmarklets that you can use to generalize some normal things you do on most websites -- e.g.

I like the idea of doing the same thing for virtually the same action over various sites, and what they do is pretty simple, each try to find a link whose name has some semblance to that particular role, then take the appropriate action; whether it's executing some javascript, going to another page, etc. Some sites work better than others, for example, hulu's log in link just uses a little javascript to show the inputs at the top of the screen, where as youtube's, will go to another screen, so is more useful.

Though all three rely on common.js to do most of the work.

As with all bookrmarklets, copy them to your toolbar, then when on an appropriate page,click one.
