Change opt+backspace binding to ctrl+backspace

I have made a ~/Library/Keybindings/ and saved something like this as DefaultKeyBinding.dict. What I would like to do is options + backward_delete with control + backward_delete but I don't know the mapping for this. Can anyone tell me?


Replace ~\U0008 with ^\U0008

~ = Option

^ = Control

\U0008 = Backspace
