Probably the displayed title in the <H1> element differs from the actual title slug you need to give in the query part of the URL.

Since WikiMedia is for example used by Wikipedia, i suggest to visit Wikipedia and observe what title slugs it uses in the URLs to the history page with respect to different languages (like Hewbrew) and "special" characters in the title (like white-spaces or ampersands, for example).

Also observe the relationship between the URL of a wiki page and the title query parameter in the URL for the history page of that wiki page.

But other commands work with the same title:

let domain = window.location.host;
let protocol = window.location.protocol;
let h1 = document.querySelector("h1");

window.addEventListener('keydown', function(event) {
    if (event.altKey && event.shiftKey && event.key === 'E') {
        window.location.href = `${protocol}//${domain}/index.php?title=${h1.innerText}&action=edit`;
    }
});

window.addEventListener('keydown', function(event) {
    if (event.altKey && event.shiftKey && event.key === 'D') {
        window.location.href = `${protocol}//${domain}/index.php?title=${h1.innerText}&action=delete`;
    }
});

window.addEventListener('keydown', function(event) {
    if (event.altKey && event.shiftKey && event.key === 'M') {
        window.location.href = `${protocol}//${domain}/index.php/Special:MovePage/${h1.innerText}`;
    }
});

Alright. Where exactly do you see this "אין פעולה כזו" error message? In your browser console, or is this part of an error page sent by the MediaWiki server?

Come to think of it, i start suspecting that, depending on how exactly you disabled the "View History" button, you did not just disable that button but the entire history view feature.

For testing my suspicion, enable the "View History" button again, and then test your script again. Does the script work then?

(And while you are at it, when the "View History" button is enabled and your script is still not working, what is the precise URL the "View History" button is using to open the history page?)

elgonzo‭ "אין פעולה כזו" is the H1 of a webpage which, according to the URL, should have been the exact webpage of the history. So, this page has the same URL index.php?title=כותרת_ראשית&action=history.
