What's Wrong?

Keybindings.json not applied on Windows desktop app

The ~/.claude/keybindings.json file is correctly configured (enter → chat:newline, shift+enter → chat:submit) but has no effect. Enter still submits. Tested after multiple full quits, relaunches, and logouts. File location and schema are correct.

Environment: Windows 11 Pro, Claude Code desktop app
Expected: Enter inserts newline, Shift+Enter submits
Actual: Enter submits regardless of keybindings config

What Should Happen?

Enter should insert a newline and Shift+Enter should submit the message, as configured in ~/.claude/keybindings.json.

Steps to Reproduce

Create ~/.claude/keybindings.json with the following content:
{
"bindings": [
{
"context": "Chat",
"bindings": {
"enter": "chat:newline",
"shift+enter": "chat:submit"
}
}
]
}
Fully quit and relaunch the Claude Code desktop app.
Open a chat and press Enter.
Enter submits the message instead of inserting a newline.
