Bug 900750 - part 5: Make NativeKey set KeyboardEvent.key value of AltRight key to "AltGraph" when active keyboard layout has AltGr key r=m_kato,smaug When AltGr key is pressed, following messages come: 1. WM_KEYDOWN for ControlLeft 2. WM_KEYDOWN for AltLeft 3. WM_SYSKEYUP for ControlLeft 4. WM_KEYUP for AltLeft In these key sequence, KeyboardEvent.key value of keydown event at #2 and keyup event at #4 should be "AltGraph". This patch fixes the key value and adding new test into test_keycodes.xul to check the behavior with SynthesizeNativeKey(). MozReview-Commit-ID: JZ6WednB8la
