Ok, here is a list of keys and their keyboard layouts:
QUERTY (US): Backquote (the "`" key, left of 1, above of tab, below Esc and the shift version is ~)
French (AZERTY?): Multiply (the * most likely, no other hints I'm afraid)
German (not sure, could be the AZERTY
): Multiply (see French comment)
Itialian (again not sure): Multiply (see above 2 comments)
Spanish (not sure): Multiply (do I need to say more?)
UK (unknown to me): Backquote (see US)
This is all from the scripts.
