On the menu bar, choose **Run, Run Configurations, New Run Configuration**. On the run configuration tab that is displayed, do the following:

1. In the box next to **Run** and **Restart**, type the name that will display on the **Run, Run Configurations** menu for this run configuration.

1. In the **Command** box, type any custom command line options you want to use.

1. To have this run configuration use the runner's predefined debugging settings, choose **Run in Debug Mode**. The bug icon will turn to green on a white background.

1. To have this run configuration use a specific working directory, choose **CWD**, choose the directory to use, and then choose **Select**.

1. To have this run configuration use specific environment variables, choose **ENV**, and then type the name and value of each environment variable.

To use this run configuration, open the file the corresponds to the code you want to run. Choose **Run, Run Configurations** on the menu bar, and then choose this run configuration's name. In the run configuration tab that displays, choose **Runner: Auto**, choose the runner you want to use, and then choose **Run**.

**Note**  
Any run configuration you create applies only to the environment you created that run configuration in. To add that run configuration to a separate environment, open the other environment, and then follow the preceding steps to create the same run configuration in that environment.
