1-What Links here and category tag

From Sterbal's Sundry Studies

I click on this link:

1-What Links here + [[category:2021]]

several times a day or more.

The Javascript link is:

javascript:!function(a){var b=document.createElement("textarea"),c=document.getSelection();b.textContent=a,document.body.appendChild(b),c.removeAllRanges(),b.select(),document.execCommand("copy"),c.removeAllRanges(),document.body.removeChild(b)}("===What Links Here?===\n\n\n");

and the Javascript places this text on the clipboard:

===What Links Here?===
{{Special:WhatLinksHere/{{PAGENAME}}}}

[[category:2021]]

is there any way to do this in shortkeys?

What Links Here?[edit]
