Ability to define additional key → escape sequence mappings
As an user I want to have the ability to define additional key → escape sequences,
so that I can use key combinations like ctrl + shift + j inside the terminal.
Maybe I just didn't find it in the documentation. For example in kitty or alacritty I can define this by something like
map ctrl+shift+j send_text all \x1b[74;5u. My application then acts when receiving this escape sequence. It would be great to do the same in GNOME terminal. Maybe this is a power user feature and for me it would be okay to configure it inside a file or gsettings.
