Say, for the following example tex document using so many professional mathematical symbols, are there some convenient ways/methods for querying latex commands corresponding to complicated mathematical symbols during typesetting.

%%%%%%%%%%%
\documentclass{paper}

\usepackage{amsmath}
\usepackage{mathtools}
\usepackage{braket}
\usepackage{stix}
\begin{document}
$\hat{\mathcal{H}}=-\frac{\hbar^{2}}{2 m} \int_{-\infty}^{\infty} \mathrm{d} x|x\rangle \frac{\mathrm{d}^{2}}{\mathrm{~d} x^{2}}\left\langle x\left|\otimes \mathbb{1}+\int_{-\infty}^{\infty} \mathrm{d} x\right| x\right\rangle V_{0}(x)\left\langle x\left|\otimes \mathbb{1}+\int_{-\infty}^{\infty} \mathrm{d} x\right| x\right\rangle V_{z}(x)\langle x| \otimes \hat{S}_{z}$

\end{document}

Thank you very much. I've noticed this tool some time before. This is really a great tool to solve the problem I posted here.
