[DOCS] Keybindings reference missing `chat:newline` action for configurable multi-line input

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/keybindings
https://code.claude.com/docs/en/terminal-config

Section/Topic

• keybindings page: Chat actions table
• terminal-config page: "Line breaks" guidance for custom keybindings

Current Documentation

keybindings currently lists these Chat actions:

• chat:cancel
• chat:cycleMode
• chat:modelPicker
• chat:thinkingToggle
• chat:submit
• chat:undo
• chat:externalEditor
• chat:stash
• chat:imagePaste

No chat:newline action is documented.

terminal-config says:

"Keyboard shortcut: Set up a keybinding to insert a newline in other terminals"

But it does not specify which keybinding action performs newline insertion.

What's Wrong or Missing?

Claude Code v2.1.47 added a new keybinding action:

• chat:newline for configurable multi-line input

That action is discoverable in release notes but not in documentation. Users who want Enter to insert newlines and another key to submit cannot discover the exact action name from docs.

Suggested Improvement

1. Add chat:newline to the Chat actions table in keybindings.
2. Include a short example config that maps Enter to newline and a different key to submit.
3. Update terminal-config line-break section to reference the exact action name (chat:newline) and cross-link to keybindings.

Suggested example:

{
"bindings": [
{
"context": "Chat",
"bindings": {
"enter": "chat:newline",
"ctrl+j": "chat:submit"
}
}
]
}

Impact

Medium - Makes feature difficult to understand
