It seems `up' is the most intuitive key to switch to the *Completions* buffer. This is how auto-completion works in web browsers - typing `down' switches from the text field to the selection list where up/down moves between candidates. Moving back from the first candidate switches back from the selection list to the text entry field. In the minibuffer this would mean `up' switching to the *Completions* buffer whereas `down' at the bottom of the *Completions* buffer switching back to the minibuffer. The bigger problem is in which order to sort completion candidates. When navigating from the minibuffer to the *Completions* buffer `up' should select the first candidate which is more natural to put at the bottom of the *Completions* buffer sorted in reverse order. OTOH, to navigate in the forward order from top to bottom the *Completions* buffer could be displayed below the minibuffer if this is possible.
