Shift-enter to insert a line break inside a command without running

[webbedspace]

It'd be nice to press shift-enter to insert a line break inside a command (such as when you type def foo [] {} and decide to insert a line break between {} without running the command.

This feature exists in most browser consoles (see: Firefox, Chrome) as well as various IRC-like places (like Twitter DMs or Slack).

Add something similar to this in your keybindings.

    {
        name: insert_newline
        modifier: alt
        keycode: enter
        mode: emacs
        event: { edit: insertnewline }
    }
