Bookmarklets
A bookmarklet is a chunk of Javascript saved in a bookmark.
When clicked, the Javascript executes.
While they can be used for other things, I tend to use them as front ends to search engines.
These are some I use frequently; the link on the left is the bookmarklet, on the right it's source page.
Right-click and select 'Bookmark this link' to add to your bookmarks.
Note: These are for Firefox
- Search Google: from Bookmarklets.com.
- Search Google Images: also from Bookmarklets.com.
- Search Wikipedia: from the wikipedia bookmarklet entry.
