Using bash version: GNU bash, version 5.0.11(1)-release (x86_64-pc-linux-gnu)
Trying to map Backspace to execute a function, I try to do: bind -x '"Rubout": my_func' This, as expected, binds the string 'Rubout' to the function. Omitting the double quotes makes bind fail. Escaping, like `\Rubout`, works neither. This is important in the case of Backspace, as there is no (to my knowledge) other way to bind the backspace than using Rubout. Using Konsole as my terminal emulator, `C-v Backspace` prints `^?` which I haven't managed to use with bind.
