pressEnterToSend: false setting has no effect

Description

The pressEnterToSend: false setting in ~/.claude/settings.json is not being honored. With this setting, Enter should add a newline and Cmd+Enter should send the message, but instead Enter still sends the message.

Expected Behavior

With pressEnterToSend: false:

• Enter → adds a newline
• Cmd+Enter → sends the message

Actual Behavior

With pressEnterToSend: false:

• Enter → sends the message (incorrect)
• Cmd+Enter → sends the message
• Option+Enter → adds a newline (this is the default behavior when pressEnterToSend: true)

The setting appears to have no effect - the default behavior persists regardless of the setting value.

Steps to Reproduce

1. Set {"pressEnterToSend": false} in ~/.claude/settings.json
2. Restart Claude Code
3. Press Enter in the input field
4. Observe: message is sent instead of adding a newline

Environment

• Claude Code version: 2.0.76
• OS: macOS (Darwin 24.6.0)
• Terminal: iTerm2 and Terminal.app (issue occurs in both)

Settings File

{
  "pressEnterToSend": false
}

Workaround

Use Option+Enter for newlines (requires iTerm2's "Left Option Key" set to "Esc+").
