Yeah, thanks for that.

The first place I looked when these questions popped into my tiny head was in the brush forum. Naturally, I missed the one sticky that might apply.

So, at your kind direction, I located said sticky, read it, and, while it is quite informative, it did not answer my buck-toothed squint-eyed questions amounting to "What's that mean...?"

But it was educational, and you have my gratitude.
