[Wine] remap ctrl, alt and command keys in osx

[projectIncomplete]

Is there any way to remap keyboard keys in wine on osx.

For example:
Right now when I press command on the (mac) keyboard I get an alt in wine.
I would like to remap the windows ctrl to windows alt so when I press command I get an ctrl in wine. This way I can command+C to copy.

I allready tried to mess arround with the registry in wine, but so far I have found no solution.
