Hello Mr. Khanda,

Let us make a new definition called "\lrp".

\def\lrp{\mathchoice
{\raise8pt\hbox to 10pt{$\leftarrow\kern-10pt\rightarrow$}\kern-9pt
\partial}
{\raise8pt\hbox to 1em{$\leftarrow\kern-1em\rightarrow$}\kern-0.9em
\partial}
{\raise6pt\hbox to
10pt{$\scriptstyle\leftarrow\kern-7pt\rightarrow$}\kern-8pt \partial}
{\raise4pt\hbox to
10pt{$\scriptscriptstyle\leftarrow\kern-5pt\rightarrow$}\kern-8pt \partial}}

And then check it please, e.g. try this definition as

$$\lrp$$
$\lrp$

$\lrp x / \lrp y$
$$\alpha^{^{\vec c}}\alpha^{^{\lrp \Gamma}} + \Gamma^{\lrp \vec f(x)}$$

I guess you wanted a similar result from TeX. For more details on
\mathchoice, please refer to "The TeXbook" by Donald Knuth.


Sincerely,
