Is there some reason you would prefer a Swing-style implementation over the approach I submitted in this PR? The Swing code breaks down if an accelerator calls for the Option modifier alone or in addition to Command. I'm still investigating work-arounds. (Long story short, Command alters the character we receive in a good way, providing a low-ASCII character even on non-ASCII layouts like Cyrillic. Option alters the character in a bad way, often producing an arbitrary symbol. Prior to macOS 10.15 we can't toss one modifier without tossing the other short of using UCKeyTranslate.) ------------- PR: https://git.openjdk.java.net/jfx/pull/425
