title: What exactly is the `#:~:text=` location hash in an URL?
body: <p>Today I noticed that some searches on Google gave me links to results with apparent instructions to highlight text.</p>
  <p>Google brought me to <a href="https://superuser.com/questions/1305867/what-is-the-maximum-size-of-a-zip-file-on-windows-10-pro-64-bit#:%7E:text=4%20GB%20size%20is%20a,about%2016%20exabytes%20size%20limitation">What is the maximum size of a zip file on Windows 10 Pro 64...</a> at the following url:</p>

  <p>I experimented a little bit further and this seems to be a feature of Google Chrome. It highlights text on the page if you append <code>#:~:text=something</code> to the URL. <a href="https://example.com/#:%7E:text=domain" rel="noreferrer">https://example.com/#:~:text=domain</a> seems to work fine, but only on Chrome (Chrome Beta on the left, Firefox on the right).</p>

  <p>The word <code>text</code> together with different characters is a bit hard to google, so I couldn't find anything on the subject.</p>
  <p>For finding out more information about these kinds of &quot;URL-hacks&quot; I want to know:<br />
  <strong>What is this feature of Google Chrome called?</strong></p>
