Forum:How to customize keys in ME2?

I just recently completed Mass Effect 1, and I've gotten very used to the way I have the key binds set up. Today I played the ME2 demo and noticed that several keys are set up quite differently than in ME1. For instance, for some odd reason they've got Use/Cover/Sprint forced into the same key mapping. I prefer having Use set as my Enter key, cover (crouching in ME1) as my right Shift key, and sprint as right Control.

I also noticed the demo for ME2 doesn't seem to have any *.ini files like ME1. Is it not possible at all now to customize your key binds? I find it so awkward using the same key to open doors, duck for cover, and sprint. If possible, I'd like to set Use, Cover, and Sprint to three separate keys each. Can this be done?

Any help at all would be greatly appreciated.
