CTRL Key combinations

hi folks,
so heres' the problem. i'm running FS2004 (US) on a Vaio laptop with an AZERTY keyboard layout(french). i know,i know, lousy set up you all say, but in France thats all i got for the time being. everthing works brilliantly......except for 1 thing only and thats the CTRL+] key combinations. bit of a bummer really cos i cant get thru some lessons without it. any suggestions on solving this one? Merci beaucoup
p.s. i've tried reassigning but it dont work
