His instructions aren't too clear, though, so let me help:
- Click the link above to go to Ecmanaut's page.
- Click the "site domain name" button, and replace his blog address with your own.
- Scroll down to the second block of code, and click and drag it into the "quicklinks" bar at the top of your browser screen -- a.k.a. the "bookmarks toolbar folder". (You might then want to right-click on it, select 'properties', and enter a suitable name, e.g. "find links".)
Then you're ready to go! Just click the newly created bookmarklet whenever you want to find any links to you on the current page. Enjoy! (And thanks, Johan!)
