Default accessibility/keyboard shortcuts for selection components?

I’d like to build in keyboard shortcuts for things like select-all in CheckboxGroup, but I’m not sure what is already present by default. Is there a reference for expected shortcuts on common components?

I’m using v23 Java

Tab / Shift + Tab are used to navigate checkboxes in CheckboxGroup.
Enter / Space bar toggle the state of an individual checkbox.

Apart from that, we don’t handle any other keys in CheckboxGroup.

okay - thanks.
