To use, install SIMBL first if you don't already have it, then simply copy YubNubSearch.bundle
/Library/Application Support/SIMBL/Plugins/ and restart Safari.
To use, type stuff into the search field. Everything will be sent to YubNub instead of Google. If the string starts with "g " it will be sent to Google anyway, with the "g " stripped off.
1.2: Skip the YubNub command when putting the first word of the search string onto the Find pasteboard.
1.1: Searches prefixed with "g " now default to Google without going through YubNub Holding down Shift no longer defaults to Google (this was behaving inconsistently) "&" and ";" are now escaped for YubNub
1.0: Initial release
