M refers to the column between L and R. M turns similarly to L, and
M' is like an R.
Grouping with parentheses helps to denote which moves should be done
together, either to demonstrate the effects of certain chunks, or for
ease of performing the moves themselves.
The d' was lowercase because it means the two layers below U.
Lowercase letters generally refer to double layer turns.
Also, Jason, why don't you perform that ELL as (rUR')(U'M)(URU'R')?
It only uses RUM moves and is super fast. The inverse is great, too:
(RUR'U)(M'U)(RU'r')
