Feature request: Allow bytes values for keyboard shortcuts

[hacker-DOM]

Hi there 👋

I am using Kitty terminal. I have mappings such as

map cmd+left        send_text all \x1b[57391u
map cmd+right       send_text all \x1b[57392u
map cmd+backspace   send_text all \x1b[57393u

In Zsh and Neovim I catch these bytesequences and execute the appropriate operation (cmd+left goes to the beginning of a line, cmd+right to the end, cmd+backspace deletes from cursor to beginning of the line).

---

The only issue I have is iPython, because there doesn't seem to be a way to map bytesequences to keyboard shortcuts. Since I have ingrained them so deeply, I end up using them in iPython as well, but often lose the entire prompt on a single invocation (that is for my most frequent one, alt+backspace, which should delete one word back)

Hum interesting. I think the handling is done by prompt toolkit, and I'm not sure if prompt toolkit allow that, so it might need a fix upstream. I'll try to check when I have time.
