That's a good question. It's been that way since it was initially
introduced in FX 2.0, and it seems at odds with the way other events are
handled.

Yes, for CTRL+a I do see it fire twice.

This does seem somewhat strange. Do you get multiple calls to your
runnable if you use a KeyCharacter combination and KeyCode combination for
CTRL-a or other key that generates a key char without needing a shift?

What is very interesting about this is that I can't duplicate it with the
"+" character.
I've added all of the following to the scene accelerators and it still
only
fires my "plus" action once for each press.
KeyCombination cmdPlus = new KeyCodeCombination(KeyCode.PLUS,
KeyCombination.CONTROL_DOWN);
KeyCombination cmdAdd = new KeyCodeCombination(KeyCode.ADD,
KeyCombination.CONTROL_DOWN);
KeyCombination cmdPlusAsShiftEquals = new
KeyCodeCombination(KeyCode.EQUALS, KeyCombination.CONTROL_DOWN,
KeyCodeCombination.SHIFT_DOWN);
KeyCombination cmdPlusFromCharacter = new KeyCharacterCombination("+",
KeyCombination.CONTROL_DOWN);
This is weird.

Using the above like this:
scene.getAccelerators().put(cmdMinus, runnable);
scene.getAccelerators().put(cmdMinusFromCharacter, runnable);
Will result in the runnable being fired twice from the same keypress.
I propose changing the accelerator processing logic so that only one
runnable gets called as the intention appears to be that a
KeyCombination
can only have one runnable associated with it, but the logic in Map
doesn't
see the above two KeyCombinations as the same key in the Map.
Note: With the second combination above I really wanted something that
worked for both MINUS and SUBTRACT simultaneously - since they both type
the same Character and only one accelerator can be set on a MenuItem.
