Why does a find field value in one application show up in a the find field of another application? On my MacBook Pro I have found that several applications seem to share the value for a find.  For example, I searched 'applestackexchange' in Safari's unified address bar, then I switch to Xcode and click into a Find field.  The first word of my search in Safari then appears there.  iTerm2 and Sublime Text 2 also seem to participate in this sharing.

Running latest Mountain Lion on  a 2012 MBP.
I've found it. It's called FindScrap. 

At the command line, enter:

defaults write &lt;program&gt; FindDialog_UsesFindScrap -bool NO


Where &lt;program&gt; is something like com.barebones.bbedit.
