Get (positive) button names from Inputmanager?

Hi,

is it possible to get the name (as string) from a button that was redefined by the user? I have a castbar with 10 virtual buttons assigned, so the user can choose which keys he wants to cast something and I want to show the keynames in the castbar.

thinking

Well, maybe the question would be helpful for other, I just came out that the user could abuse this and define 1 key for all buttons, so I will make fix buttons that can't be accessible.

thx anyway :)
