It's a word in the LAYOUT dialect that says the data being provided to
the LIST is in a block:
http://www.rebol.com/docs/easy-vid.html#section-16
The word is perhaps redundant in that it looks like it could be inferred
from context. But perhaps not -- perhaps it acts to avoid some possible
ambiguities when parsing the LAYOUT dialect.
Because it is a word in the LAYOUT dialect, you won't find it with HELP
-- any more than you'd find ACROSS or TEXT. Perhaps HELP should be more
helpful for built-in dialects like LAYOUT.
