There is no shortcuts for selectNextChangeLead and selectPreviousChangeLead in Aqua LAF which updates [LEAD_SELECTION_PATH_PROPERTY](https://docs.oracle.com/en/java/javase/24/docs/api/java.desktop/javax/swing/JTree.html#LEAD_SELECTION_PATH_PROPERTY).....
Other L&F uses "ctrl DOWN/UP" to selectNextChangeLead/selectPreviousChangeLead but same shortcut cannot be used in mac as "ctrl DOWN" shortcut is used to display the window of current active application while "ctrl UP" is used to display all windows of all applications which allows to switch between them
so used CTRL+SHIFT+DOWN for the selectNextChangeLead CTRL+SHIFT+UP for selectPreviousChangeLead

No regression test as it can be verified through SwingSet2 demo as below..

With ctrl+shift+down
