NumpadAdd does not match plus-key hotkeys

TanStack Hotkeys version

v0.10.0

Framework/Library version

v19.2.5

Describe the bug and the steps to reproduce it

When registering a plus-key hotkey, the shortcut works for the main keyboard plus/equals key path, but does not reliably match the numpad plus key (KeyboardEvent.code === "NumpadAdd").

This makes it difficult to support common app shortcuts such as zoom in with Mod + +, where users may reasonably press either the main + key or the numpad + key.

Steps to reproduce:

1. Register a React hotkey for a plus shortcut, for example { key: "+", mod: true}.
2. Focus the page.
3. Press Ctrl + NumpadAdd on Windows/Linux, or Meta + NumpadAdd on macOS.
4. Observe that the hotkey callback is not invoked.
5. Add a native keydown listener and inspect the event; the browser emits event.code === "NumpadAdd" and event.key === "+".

Expected behavior:
A plus-key hotkey should match numpad plus as well, or the docs should describe the recommended way to register numpad plus separately.

Actual behavior:
The app needs a separate raw keydown escape hatch for NumpadAdd.

Terms & Code of Conduct

• I agree to follow this project's Code of Conduct
• I understand that if my bug cannot be reliable reproduced in a debuggable environment, it will probably not be fixed and this issue may even be closed.

Start with the linked CodeSandbox and compare the registered plus shortcut with native keydown events for the main plus key and NumpadAdd. Trace the hotkey matching path used by the React registration and verify completion when Ctrl or Meta plus NumpadAdd invokes the callback without requiring a raw keydown escape hatch.
