Question: just switched from single to dual monitors

have managed to utilise both screens with emacs by using `C-x 5 f` to open a file in a buffer in a new frame, i can drag that frame on to the 2nd monitor and enjoy my extra real-estate

Prob I now have is how to efficiently switch between buffers in different frames

I'm used to using `C-x o` to switch between buffers in a split frame on a single monitor but this doesn't work for multiple frames

Having to use the more cumbersome `C-x 5 b <buf-name>` which is painful in comparison

Anyone have any top-tips on how to make buffer switching more efficient across dual monitors?

Ideally I would like to cycle across all buffers using a single simple keyboard shortcut regardless of frames

Answer: 
I'd expect `C-x 5 o` to switch to the other frame, tho I don't have such a dual-screen setup to verify.
Maybe

```
(global-set-key (kbd "C-x o") 'next-multiframe-window)

```

(Though as spike mentioned, I think keeping `C-x o` bound to `other-window` and binding `next-multiframe-window` to something different makes sense.)
