I'm using a Surface RT, and there's no easy way to take a screenshot. The Print Screen key is excluded from the Surface's Touch Cover keyboard, so to take a screenshot, I have to plug in another keyboard. It's a little ridiculous. And of course, because it runs Windows RT I can't just write an AuotHotkey script that would fix the problem, since you can't use x86 applications.
Is there a way to change the Page Down key (or Page Up, either will work fine), to the Print Screen key via a registry hack or something? Those are the only two keys that I never use, so those are the only options for changing. I could probably live without the "Tilda" key, but sometimes I think I do need that one. Even better, it'd be great if I could have something like Shift+Page Down to trigger print screen, but that's getting in to a more complicated territory that I'm not sure the registry could handle.
