Spanish upside down "?" with Finnish keyboard?

Hello I am happily using Suse 8.1 (KDE3) but I need to practice my Spanish. I was glad to note that [AltGr]-1 produced the Spanish questionmark upside down, but unfortunately [AltGr]-+ is reserved for "\" (the key next to "0" in the top row, 2 left from backspace). Is there another way to do that with Finnish QWERTY layout and if not, how to fix the X/KDE keyboard mapping to do that? Cheers, -- --Jyry C:-( C:-/ C========8-O C8-/ C:-(
