How do I copy a tab's title in Chrome?

Use a bookmarklet:

javascript:window.prompt("Copy to clipboard: Ctrl+C, Enter",document.title);

Credit for this window.prompt trick goes to Jarek Milewski. This bookmarklet also works in ANY browser, even Netscape 3, and not just Chrome.

Add a bookmark by hitting CtrlD or clicking on the star on the right end of the address bar.

Copy title.

Click on "Remove".

This can be achieved through the page source code:

1. Right click on the page and select 'View Source'
2. Look for the <title> tag
3. Select and copy the text.
