Refine naming convention for key-labels?

[urob]

Context

I am debating whether to further refine the key-label naming conventions. Currently, there is a convention in place for boards with 4 to 5 rows. But there isn't yet for larger boards.

Key-positions without a clear convention

• What's a good name for the row above N? For the glove80, we have used C (for ceiling). I also like F (for function keys, as this is what it usually would be used for)
• What's a good name for the row between B and H? For the glove80, we have used F (for floor).
• What should be the columns labeled inside of 0. Something like C (for central)?

EDIT: Upon further consideration, there aren't really that many boards currently affected. So might be easiest to just refine as we go.
