How to disable block identifier in upper right corner

[Strahan]

Hey.. I was goofing around in the inventory view while in creative mode and I press I. When I exited inv, I noticed I now had a display in the upper right corner that would tell me what the block is that my reticule was hovering over. I tried doing I again in inv to toggle it off, but it still is there. How do I get rid of that?

Also, when in inv if I search for "lapis" for example, I do not see covers/corner strips/etc. I inadvertently discovered that they are still available, just under 750 instead of Tekkit classic's 136. Is there a way to get the creative mode item browser to show those?

Thanks!
