Select next bone child, Shortcut.

Hi Ronald,
thank you very much for your support request. Yes, there are shortcuts to navigate the parent-child hierarchy of the bones (they are bound to the numpad buttons by default). The shortcuts are shown when hovering the mouse over the corresponding button in the UI or by clicking on "Edit --> Preferences" in the Clip Editor (that's where you can change them).

Here is the manual page describing the corresponding UI: https://www.soxware.com/umotion-manual/Selection.html

Please let me know in case you have any follow-up questions.

Best regards,
Peter
