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. The source is here:


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.
