Simple, small, free applescript program that lets you enter a search term, and then copies that term to the clipboard. Then, when you invoke Spotlight or Find, you can Paste the term into the search field.
You'll be amazed at how much faster things work!
Of course, there is no need to have this little app. It just makes life a little more convenient. Try just pasting in a search yourself first to see how much faster this is than typing in the term, one character at a time.
Mac OS X 10.4 PPC
||Script should work with any Mac, although its intended use is for 10.4 or greater.
