So adding arrow notations would only be to strike this expression like in the cancelto case (one can still use "normal" text to draw arrows in token elements). The package documentation does give much indication about how this notation is used and how popular it is, but it is interesting to note the feeling of the author: "Drawing slashes through math to indicate “cancellation” is poor design. I don’t recommend that you use this package at all" So it does not really seem essential to add more notation beside updiagonalstrike, which has a concrete use case... -- Frédéric Wang maths-informatique-jeux.com/blog/frederic
