Annoyances.org has an article on how to kill Clippy (the MS Office assistant) with a little registry hack. Ahhh, much better.
One of the great features about the Opera browser is the quick searches that can be made by typing a shortcut in the address bar. For example, "g searchterm" searches Google.com for the search term.
While Opera come pre-loaded with some great shortcuts, some are missing (namely, an IMDB search would be nice). There is no native UI to edit these shortcuts. This is where the The Opera Search.ini Editor comes in. It allows you to graphically edit the search shortcuts and can integrate into Opera to allow you to add new searches.
