Click it, and you will be asked for a name and description. The track or data choices you made will be saved. You can reload them using the 'Load configuration' button.
It's that simple!
Once you save configuration for more than one page, you might want to create a configuration set. This allows you to save your selections for several views at once. Click on the Manage configuration tab in the configuration menu to do this.
