Cannot handle backspace

[shirobachi]

Hey,

I am trying to handle backspace key by coding this

await self.bind("backspace", "debug('dot')")

I read that backspace is alias there also I tried ControlH after read this.
I wrote there are only one capitalize version but tried many :D

Maybe I can use ASCII code? If I can, can I ask kindly how?

Thank you in advance for help 🥺
