ETO Studio provides a command similar to the Find in Files command. It is on the Visual Studio menu bar.

Find and Replace Find in Intent Search Path.
This command is a wrapper for and provides the same options as the standard Find in Files command. The Find in Intent Search Path command provides an easy way to automatically set the list of search directories to the current Intent search path.
When invoking the command with an open solution (containing an ETO project), the Find in Intent Search Path function sets the list of directories to the search path for that solution.
When invoking the command with no solution (or no ETO project) open, the Find in Intent Search Path function sets the list of directories to the default Intent search path.
