Research direction

Start by tracing how prompt-toolkit reads stdin and turns input into key events, then compare that path with the existing ESC and Enter key binding handling. Done means a documented or implemented way for \x1B\x0D from stdin to trigger the same bound action instead of being inserted as visible characters.

Description

IPython uses prompt-toolkit and I'm trying to send code to an IPython console via standard input. IPython binds ESC, Enter to execute code. Is it possible to configure prompt-toolkit somehow to process keybindings seen in stdin? If I send \x1B\x0D, the characters appear on-screen; I'd like that to be the same as if I pressed ESC and then Enter.
