what key is question mark on Brazilian language keyboard?

[recife]

when switching between English and Brazilian Portuguese keyboard cannot find
the question mark which key or combination of keystrokes will give the
question mark symbol when typing in Word? (Windows XP)

Alt-Ctrl W
If you can use Portuguese, it's a more convenient Shift minus (next to the
zero).
