You can replace all occurrences of a specific string or regular expression with the return value of a BeanShell script if the Return value of a BeanShell snippet radio button is selected in the search dialog box.

You can use this, for example, to replace each occurrence of <quote>Windows</quote> with <quote>Linux</quote>, and each occurrence of <quote>Linux</quote> with <quote>Windows</quote>, by searching for the following regular expression:

`(Windows|Linux)`

And replacing it with the following BeanShell snippet:

`_1.equals("Windows") ? "Linux" : "Windows"`
