Ofcourse you can costumize the actionbuttons, just go into options then controls. Good luck to you!

Unfortunately, those keys are not mappable in the control menu, and I haven't found a way to do it in any ini file. Sorry.
Really, i just asumed that it was possible to map every key, kinda strange actually. You should call their customer support and ask if there is any way to remap them.
