In the Tool Order tab in Site Info:
Verify you can change a title and add a U or u and D or d.
Verify you can still use U or D for reordering when not in tool focus (aka not editing a tool title).
After the change on SAK-32654Laura Cira noticed that you can't use the letters U or D in a site title rename, it ends up just moving the section up or down. The a11y fix probably shouldn't be active when a input text area is focused.
