Help for center commutators (Big bld)

[Underwatercuber]

So I need some help with big bld center commutators. So far it seems to use a commutator you do [A,B] where A is a slice move moving your first target to your second target and B is a move inserting your third target into the position of the second target. I am having some struggles with having multiple targets on the same layer as well as targets on the bottom layer. I have also heard of inverse comms [B,A] but I am not sure in what cases it would be needed to apply them. Thank you in advance for help

Thank you! Those help a lot.

I have a question about this commutator I came across today
[M:[Rw U' Rw' U]]
is that a typo? If not do I execute it as M Rw U' Rw' U Rw' U Rw U' M'?
Its supposed to be Uf -> Ur -> Bu
