Is there a key stroke to switch to a fullscreen app in Lion? I normally switch around my virtual desktops using the ctrl+num. Now, Exposé shows all the desktops and the fullscreen app whereupon clicking the fullscreen app rectangle will take me back to it. I'd rather do so via keyboard nav. cmd+tab doesn't work for me because I'm doing this with VMware where I have multiple windows open, one is fullscreen, others are not. cmd+tab seems to land me on whatever VMware window it randomly chooses.
You can configure these shortcuts in System Preferences -&gt; Keyboard -&gt; Keyboard Shortcuts -&gt; Mission Control

I think the default is control-option-left/right arrow, at least that's what I have it set to.

In mission control, you can also re-order the position of the desktops/full screen apps by dragging them around. I think by default they're ordered by most-recently used desktop, but you can change that (I can't remember how, that would be a separate question anyway).
