How are Mnemonics On Buttons Supposed To Work?

[Mark Fortner]

Recently, I added mnemonics to some buttons and enabled mnemonic parsing,
and noticed that the mnemonic isn't rendered.  I came across this issue:
https://javafx-jira.kenai.com/browse/RT-18849

which seems to indicate that NOT showing mnemonics is the expected behavior.

If that's correct, how are user's supposed to know what mnemonics are
available?


Cheers,
