by the way, how to delete the attachment? I think there should be a "delete" button in the Manage Attachments window, but only "add" button is found.

I used one of my favorite commands, but had to "fudge" it a bit . . .

The command \rlap{x} prints the*x*over the next character.

\rlap{A} \int

. . $\displaystyle \rlap{A}\int$

\displaystyle \rlap{A} \int

. . $\displaystyle \displaystyle \rlap{A}\int $

\displaystyle creates a larger integral

. . but the $\displaystyle A$ is not centered.

\displaystyle \rlap{\;A} \int

. . $\displaystyle \displaystyle \rlap{\;A}\int $

\; inserts a space before the $\displaystyle A$.
