As you can see from Terry's screenshot, the buttons ARE there and can be selected by moving the cursor and clicking. But, yes, you are correct, you cannot move from an entry to the delete/rename/up/down via tab or shift+tab.
If on your screen the buttons are not present, we will need an actual screenshot to see what you're referring to and possibly the cause. The loss of keyboard functionality for move/rename/delete is a different matter entirely and of course can be solved (in reality, this is the correct behavior, as toolbar buttons should not be tab selectable and should instead have hotkeys such as alt+something).
