> I think readline might actually disable kernel interpretation of some of these control characters when it starts accepting input, and then re-enable them when it stops, but I've never looked into that.

Canonical mode means the kernel/terminal is line-buffered and line-editing is handled by it; non-canonical mode means user input is pushed to the application immediately.
