Creating a Macro for Spacebar to Autojump

[Pazool™]

Hey guys was wondering how I would go about setting up a Macro for my spacebar so that I only have to hold it down and my character will continue to jump? I am looking at this for something like TF2 where there is BHopping and such. I recently started playing surf and it really interested me, I also saw some people BHopping to gain speed. I have tried the mousewheel to jump approach and it was just too hard to get used to. If it helps my keyboard is a Mad Catz Cyborg V7 and does have its own Macro software, but only for the programmable buttons on the sides. Really appreciate any help I get. Thanks :D
