Type a # character in the page content followed by a tag name to automatically turn it into a tag link. The link text can be set based on the key value in the .\lot\x\hash\state.php file:

Key	Result
hash	Link text will be the name property of the Tag class instance preceded by a # character. When you hover over it, the title property appears in the tooltip.
title	Link text will be the title property of the Tag class instance. When you hover over it, the hash tag (the name property preceded by a # character) appears in the tooltip.
*	Where * is any string, link text will be the * property of the Tag class instance.

If the key value is a callable function name or an anonymous function, the value returned by that function is used to replace the hash tag pattern:

<?php

return [
    'key' => function (string $text): string {
        // In this context, `$this` refers to the instance of the `Tag` class
        return '<a href="' . $this->link . '" rel="tag">' . $text . '</a>';
    }
];

If you want to set its value as a function name, make sure that it cannot possibly exist as a property name of a Tag class instance, to prevent it from triggering a property call. You can do this in a number of ways, such as creating a long and unique function name, or creating a function name under a namespace. As long as a function name contains a \ character, there is very little chance that it will be detected as a property name:

function name(string $text): string {
    return '<mark>' . $text . '</mark>';
}

// This will most likely return the `$tag->name` value, not the return value of the `name()` function
return ['key' => 'name'];

Any hash tag pattern found in the HTML tag (as a tag name, attribute name or value) will be ignored. Any hash tag pattern found in the HTML content of <code>, <kbd>, <pre>, <script>, <style>, and <textarea> will also be ignored.
