To enter text into the terminal, open up a file using your destop (like
say /etc/passwd), select one letter, then middle click in the terminal.

To change consoles without a working keyboard, use the chvt command.
E.g. use copy&paste and:
sudo chvt 1

If your boot to a lower non-X runlevel and run:
can you Ctrl-Alt-BackSpace the server?
