Ah, yes, of course -- having not ever directly used just the VGA console
on any Xen host I do tend to forget that it is more limited.

So that text should probably start with:

 	On a serial console, one can type the escape character [[....]]

From what I see in the Xen code it wouldn't be hard to add PS2 keyboard
support to Xen, but these days I suppose there wouldn't be much point.
(and adding USB support, even just for a keyboard, would probably
require quite a bit more code with quite a few more hardware specific
quirks and other such difficulties)
