You're getting close, just need a few adjustments.
Instead of using the `hostname` property, I prefer to use `host`, because it also includes the port (in case the URL has one) - check the [documentation](https://developer.mozilla.org/en-US/docs/Web/API/Location/host) for more info.
You should also get the `protocol` (which can be `http`, `https`, etc), to build the full URL. Without it, you might not get what you want: suppose the current page is `https://software.codidact.com/posts/286256`. If I run this code:
```javascript
let domain = window.location.host;
window.location.href = domain + '?abc=1';
```
The result will be the URL `https://software.codidact.com/posts/software.codidact.com?abc=1`. Only by including the protocol at the beggining (before the `domain`), I get the correct URL (`https://software.codidact.com/?abc=1`).
To set the URL you should use `=`, not `===` (the difference is explained [here](https://software.codidact.com/posts/282893)).
Not sure how you're using the `h1` element, I guess you wanted to get its text? I included an example below, that gets the `innerText` property, which contains whatever text is inside the `h1` tag.
And finally, when the `shiftKey` property is set, the corresponding key will be uppercased, so instead of checking for `e`, you actually should check for `E`.
The final code:
```javascript
let domain = window.location.host;
let protocol = window.location.protocol;
~~let h1 = document.getElementsByTagName("h1");~~
window.addEventListener('keydown', function(event) {
if (event.altKey && event.shiftKey && event.key === 'E') {
window.location.href = `${protocol}//${domain}?title=${h1.innerText}&action=edit`;
}
});
```
Note that I used [template strings](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) to put the variables values inside a single string. Note that the delimiter is the character <code>`</code> - you're using double quotes, so `"domain?title=h1&action=edit"` doesn't put the value of the `domain` variable in the string (instead, it puts the word "domain", which is not what you want).
But you could also use old-style concatenation:
```javascript
window.location.href = protocol + '//' + domain + '?title='+ h1.innerText + '&action=edit';
```

I already knew the difference between assignment and comparison, I was just wrong.
