"Page Up/Down" in Traktor 2?

I have googled all over the place and can't seem to find an answer. Is there a way to hit page-down or page-up in the track browser in Traktor? If I could do that, I wouldn't have to constantly go over to the computer and use the mouse on the tiny little scroll bar thing, and I would have a chance of actually scrolling through a library with more than 3 pages of tracks in it.

I understand that I'm "supposed" to organize things into playlists/"crates" and folders and blah blah blah in traktor but that is just plain not how I want to play when I'm using my full library. I want to page through it a page at a time.

I am honestly pretty amazed that Traktor doesn't seem to provide a mechanism to do this, unlike literally every other piece of software I interact with. I'm also confused as to why I'm the only one who seems to consider this a problem... isn't it awkward as hell to be constantly going over to the computer keyboard/mouse while you're trying to be a controllerist?

I'm using Traktor 2.mumble on OSX, a VCI-100SE and the DJTT Mapping. But I believe my question is a general question about Traktor?
