#24049

Powered by Codex Action

I checked the public repo side and this looks closely related to #24049.

The public code already exposes the low-level keymap settings needed for this behavior:

[tui.keymap.composer]
submit = "ctrl-enter"

[tui.keymap.editor]
insert_newline = "enter"

For the desktop app settings UI, the clean app-server write path would be a single config/batchWrite call so both bindings switch together and loaded sessions hot-reload the updated user config:

{
  "method": "config/batchWrite",
  "params": {
    "reloadUserConfig": true,
    "edits": [
      {
        "keyPath": "tui.keymap.composer.submit",
        "value": "ctrl-enter",
        "mergeStrategy": "replace"
      },
      {
        "keyPath": "tui.keymap.editor.insert_newline",
        "value": "enter",
        "mergeStrategy": "replace"
      }
    ]
  }
}

Switching back to the default Enter-to-send behavior can clear those two overrides by writing null to the same key paths through config/batchWrite.

I do not see the WinApp/Electron settings-page source in this public repo, so the actual UI toggle likely needs to be wired in the desktop app codebase. If maintainers want a public-repo PR, the most relevant change here would be adding docs/tests around this app-server keymap preset so desktop clients have a stable reference for implementing the setting.
