Well, not exactly everything, D76 - it doesn't work in Word, for instance - it makes any selected text very small, like subscript - if you use "command +". But it works in lots of programs - Photoshop - most things Adobe, Dreamweaver (though the text is pretty much unreadable if you zoom in) Strangely, it does NOT work in Pages and in Keynote it actually enlarges the font in your document, rather than zooming in on the document. In Entourage, it adds someone to your Address Book.
