Chrome: Keyboard shortcut to leave address bar and focus browsing area?
[EDIT:] Does simply pressing Tab a few times work for you? [/EDIT]
There doesn't seem to be such a shortcut. What you can do is press CTRL+F, search for a word close to where you are on the page and then Esc.
Of course this is not really convenient, so you could also do what this other answer suggests and type javascript:
in the url bar, followed by Enter. This executes the javascript following the colon, so it does nothing. However, it DOES refocus the page.
This is still not convenient, but using AutoHotkey, you can remap any shortcut you'd like to do this. The AutoHotkey Script would probably have to simulate CTRL+L to make sure focus lies on the url bar, followed by javascript: and Enter.
I hope this helps. Sadly, AutoHotkey is only available for windows but there might be a similar tool for Mac.
Another option I just found out about: On windows, I can press Alt followed by Tab. This might work on mac as well.
There's no good way to do it, but if you're focusing the address bar to copy the URL, you could install something like Vimium, it ads yy
hotkey that saves the URL to the clipboard.
