comment Change the orientation of Arrow of xtwocell in the 2cell option for xy
how do you shorten the arrow? I didn't understand your instructions about adding the keys "shorten >" and "shorten <"

comment Label the source/target object in the middle of compositemaps from 2cell package of xy?
That adds $B$ to the [0,1] matrix position. It's not where the arrows are pointing to/from. If I change the curvature of the compositemap, I can get the arrows closer toward pointing to $B$, but it's never quite right. Also there is not enough space between the two arrows for a $B$, let alone a longer expression.

Yes, that arrow does look shorter, and does not span the diagram.

comment Change the orientation of Arrow of xtwocell in the 2cell option for xy
In your diagram, it seems like the doublearrow spans from the lower-left corner to your invisible node. But typically we want 2cells to be shorter, hovering somewhere in the center of our commutative diagram. Sorry I can't be more specific, but I can say that the 2-cells displayed by the 2cell package are the right size (not surprising since 2cell was invented by a cat theorist for his book). If I can get a 2-cell of the size given by 2cell, but with the direction given by your tikz-cd example, then I will be happy. I did not understand your instructions about the shorten > keys, though.

Yes, I would consider using this package. Is it possible to make the double arrow shorter? Seeing a 2cell span the diagram like that is a little jarring.

comment Interior product (contraction) symbol
I'm reading a paper which uses \rfloor (it's on arxiv so you can read the source), but it looks terrible and nonstandard.

comment Interior product (contraction) symbol
@Seamus: I'm not sure how to find symbols on the web, but if you go to the amazon page for "Smooth Manifolds" by "John Lee" at amazon.com/dp/0387954953 then choose "Search inside another version of this book" and then search for "interior multiplication", you will see the symbol near the top of page 335 in the first result.

comment Interior product (contraction) symbol
@egreg: Ok, I think you're right. Except it's an inverted, not reversed, negation symbol. I originally said that the inverted negation was incorrect, but some further googling suggests that some people actually do use that notation for interior product. However it remains true that several texts I'm familiar with use a somewhat different notation with longer strokes than a negation symbol. So there are at least two alternative symbol choices for this operator. I prefer the longer one, and am still seeking the correct markup (it may be \righthalfcup from MnSymbol though)

comment Interior product (contraction) symbol
@Werner: That link does describe the mathematical operation I'm seeking. It shows one notation with no typesetting difficulties, which is a subscript on an \iota or i. There is an alternate notation which is what I'm looking for, which is not mentioned in that link.

comment Interior product (contraction) symbol
Are there issues with using the MnSymbol package? I found this thread tex.stackexchange.com/questions/17370/… Should I try to find the same symbol in another package?
