Flex的新插件BluePrint,主要是方便查找代码的，但查找范围不仅限于ActionScript和MXML。它支持联网查询。快捷键Alt+B
Blueprint is an innovative code-centric search application, initially delivered as an Eclipse plug-in. It is a custom search tool that searches only for code (for now, it searches just for MXML and ActionScript). So, for example, if you search for DataGrid, it returns a set of code examples that use the Flex DataGrid control. But what's really cool is that you can easily highlight, copy, and paste chunks of code right into your application, all without leaving Flex/Flash Builder.
