What exactly do these hold-over arrows in OS X 10.9 do?
When I mistakenly press on the right arrow, it just starts flashing/blinking, and the other arrow — the left one — appears to indicate that it's now available, too. Yet nothing at all happens, not even any kind of title or annotation is provided.
The right arrow stops blinking and the left stops being bold if you navigate away from the folder, and then go back.
These arrows are really annoying; more worryingly, I'm afraid they're doing something bad behind my back. How do I turn all of this nonsense off for good?
Also, if mistakenly pressing them may have caused any damage I haven't noticed yet, how do I undo any such damage?
