Shift+Enter: Insert Newline in Claude Code (WSL2)

Problem

Shift+Enter doesn't insert a newline in Claude Code by default when using WSL2, whether in VSCode's integrated terminal or Windows Terminal.

Fix: VSCode Integrated Terminal

Run /terminal-setup inside Claude Code from the VSCode integrated terminal. It will automatically configure the keybinding.

If it says "Found existing VSCode terminal Shift+Enter key binding. Remove it to continue.", remove any existing shift+enter entry from your VSCode keybindings.json (C:\Users\<you>\AppData\Roaming\Code\User\keybindings.json) and run /terminal-setup again.

Fix: Windows Terminal

Windows Terminal needs a separate keybinding. Add this to your Windows Terminal actions array in settings.json (C:\Users\<you>\AppData\Local\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\LocalState\settings.json):

"actions": [
    {
        "command": {
            "action": "sendInput",
            "input": "\u001b\r"
        },
        "keys": "shift+enter"
    }
]

Then restart Windows Terminal. Shift+Enter will now insert a newline in Claude Code.

Fallback (no setup needed)

Use \ + Enter to insert a newline — works everywhere without any configuration.
