Browsing iBooks using keyboard?

Is it possible to turn pages and such with the keyboard dock accessory from Apple?

I'm sitting on the couch with the iPad plugged into the keyboard dock, typing something into Notes, and I get the idea that I want to read a chapter or two in iBooks. So I simply launch the application and it's actually pretty comfortable sitting on the couch with the ipad sitting on my dinner tray plugged into the keyboard. It would sure be nice to sit back, and tap the space bar on the keyboard to turn a page in iBooks.

Any ideas?
