Today I embedded two Javascripts into my template and by pure coincidence both are Google-related.

Highlight incoming search queries

First is searchhi by The Daily Kryogenix. It's easy to install (just don't forget to modify your CSS) and works reliably.

N.B. Note however that apart from Google searches this script also recognizes Yahoo, AllTheWeb and any other search engine using appropriate query format.

Block Google AutoLink

Second script has a different goal – it blocks Google Toolbar's AutoLink feature using its smart rewriting code. The script itself came from this ThreadWatch post. You can read why Google is Evil and why is it so important to ban AutoLink (a.k.a. Microsoft SmartTags) at BBC, Left Brain/Right Brain and numerous other sources.

P.S. And here is some more Javascript to detect if a user has Google Toolbar installed.
