New buttons?

I have noticed a set of buttons in the animated texture buttons that, if memory serves, were not there in the last version. Just a couple of rows of blank buttons(?). Does anyone know the function of these?

I couldn’t find them.
Could you tell me which version and which window?
the texture animation buttons i know about are in the texture buttons and the UV image window

They are in the texture window. I was mistaken when I said they were blank,…they say ‘Fra: 0’. Then there is another button beside each labelled ‘0’. 4 of each, 8 alltogether. version 2.28a.
