研究方向

Investigate how jwerty currently handles keyboard events in its source code (likely in the main library file). Look for any existing modifier key detection. The feature request is to add a method like $.jwerty.is('shift') that checks whether a modifier key is pressed. The implementation would likely involve storing the state of modifier keys during keydown/keyup events and providing a simple API to query them. Check the comments on the issue for any additional context or suggested approach.
