If it was a Valve game(Half life, or Source engine) it would be a simple matter of typing "Bind (key) tm" in console. But sadly I don't think Beth's engine lets you bind through the console.
In other news, Todd Howard has acknowledged that they knew the PS3 would have memory issues before the game was released. They just thought it would only effect a limited amount of people. What irks me is the fact that they make it sound like it's the PS3's fault, when in truth the PS3 is just as strong or stronger than the 360. I strike it up to developer lazyness
