Page Up or Page Down buttons move you either up or down one screen at a time. One tap per screen.
On a keyboard with Function buttons (The F keys at the top of the keyboard):
F11 enlarges the browser to full screen size. Press F11 again to return to regular size.
Ctrl F (hold down the Ctrl with your left pinky and tap the F letter key) will bring up a Find/Search box. This is great in long threads when you want to find something in particular.
