I'd also use this on reply screens, where the parent comment is given for reference, but then I realize I need to check something in the parent's parent...

Err, I'm a dork. Comment post pages *do* have that link ("In reply to:"), and I use it all the time. It'd be handy sometimes on main comment pages too. (Though probably shouldn't take up a whole line -- maybe a little "^" link that scrolls rather than opening a new page?)
