I recently discovered this completely by accident, and had no idea they had added this feature to Safari (or when).
Two-finger double-tap on the trackpad with your cursor over a <div> on a webpage, and Safari zooms in on that section. Really cool shortcut for instant readability if you're using a laptop at arm's length.
