Notes

"Some key events, or their values, might be suppressed by the IME in use". On mobile (virtual keyboard), for every key Blink and WebKit based browsers report "Unidentified", Gecko reports "Process".

1. Partial support refers to these versions of Firefox returning "MozPrintableKey" for all character keys.

2. Has non-standard key identifiers and incorrect behaviour with AltGraph.
