Feature Request: configuration option that makes ENTER insert newline instead of submitting prompt

[ntc2]

Context

There are currently roughly 7 open and 18 closed issues related to users having trouble with the default "submit prompt on ENTER" behavior: https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20submit%20enter (not all, but nearly all of these issues are related to ENTER behavior).

There is a popular issue (currently 25 comments) where someone requested changing the default behavior so that ENTER doesn't submit prompt, and that was closed as wontfix. And here is another issue where someone asked about how to make ENTER insert a newline. And here is a more general issue concerned with multiline prompts. I understand it's not possible to change the default.

Feature Request

Here I'm asking for the option to configure a non-default behavior, where ENTER inserts a newline without submitting the prompt, and some other sequence (e.g. CTRL+ENTER) is needed to submit the prompt. Here is another issue requesting the same thing.
(I would also like this option in the web UI for Claude, but I realize that's out of scope here.)

For example, Slack has a configuration option and Mattermost has a configuration option to make ENTER insert newline and CTRL+ENTER send messages. In Claude Code, this could be available via a slash command, e.g.

/multiline-mode on

and when this is set, the ? help could show that CTRL+ENTER sequence is needed to submit the prompt. I would want this config setting to persist between Claude runs, e.g. by being stored in the ~/.claude/settings.json.

Currently Supported Ways to Enter Multiline Prompts

These are workarounds, but don't solve my problem.

Summary of currently supported ways to enter multiline prompts:

• ALT+ENTER: works for me
• SHIFT+ENTER: many people report this doesn't work for them and there is a tracking issue here; it doesn't work for me
  • running /terminal-setup first may help, but it doesn't help for me
• insert backslash (\) at end of line before ENTER: works for me

However, note that none of these are very ergonomic, since they all require extra work for every newline in the prompt.

shift-enter++ That'd be my choice.

shift-enter is what I expected and keep hitting based on muscle memory

I can confirm that the key binding added by /terminal-setup in keybindings.json for Shift + Enter on VS Code doesn't work for me either. Alt + Enter and \ both work.

Support for Shift + Enter would be ideal

To clarify, there are a few comments mentioning SHIFT+ENTER to insert newline without submitting prompt: that is a different issue, e.g. tracked here. This issue: I want an option to make plain ENTER insert a newline without submitting the prompt. The sequence to submit the prompt could then be CTRL+ENTER.

I really want this option!
It’s super inconvenient for speakers of languages like Japanese, where we use Enter a lot when writing, to have it submit with Enter.

I am also in this camp. Please let us turn off Enter as automatic-submit. I'd much prefer a key combination in order to submit commands, considering that it wastes tokens if you do it prematurely. Shift+Enter would be fine, but that didn't work for me, either.

CopilotChat.nvim uses CTRL-s to submit the prompt (mnemonic is "submit").

Shift+Enter camp here.

Rationale: muscle memory from ChatGPT, Claude AI, WhatsApp web, Signal desktop, Discord, Slack, Telegram web, Telegram desktop, Skype, Twitter DMs and almost every single "chat" app in the whole wide world...

I noticed recently using Claude Code within a Jetbrains term, Shift-Enter now does work for newlines (and Enter for submit).
