On Windows, this is correct for ALT.
If you don't want to handle ALT on Windows, you might want to close this.

In the Korean version of Windows, AltGr is used to convert between Korean and English, so this is correct, but I'm not sure about other versions of Windows.

Then I guess we need to make it possible to distinguish Left ALT or Right ALT next time.
