Searchling is a free, quick and unobtrusive way to access your favorite search sites in MacOS X. Once running, Searchling appears as a small icon (the 'G', for Google) in your menu bar alongside your other menulings. Click the icon and a small text field and two pop-up buttons will appear. Enter your search and hit return...poof, you've got results in your favorite Web browser. The source code is available.
What's new in Searchling
Version 1.1 adds the following:
Sites definitions now sorted in Application Support directory
Easier to edit, won't be overwritten with newer releases
Displays warning if you mess up the sites.xml file (and uses defaults)
Clicking the menu icon while its displayed will toggle it
Better support for right-clicking on the menu icon (not perfect)
This has got to be one of the more frequently used apps on my machine. I don't understand why it's no longer available for download. If Ambrosia really thinks they can add value that's actually worth buying, they would would allow the continued distribution of this app.
Anonymous, you are missing something: the point is that you can (and should) customize it to search in your prefered search engines, *not* only in Google! - Anyway, meanwhile it has been assimilated by Ambrosia :-(
