The first entry in the Option Groups tree is 'Import' settings. These settings are specific to the import script. The second entry is 'Build' settings and apply only the build script.

Controlling the various settings is done in the same way as for the 'Configuring Arguments' dialog window described under "7.6 Plug-ins". There are two previously unseen controls: the Spinner and the CheckList.

The spinner is like a text field in that you can type into it and use the checkbox to enable it. However, it only accepts numeric values, and only within a certain range. For instance, the verbosity argument only accepts values in the range 0-3 inclusive. The two small up and down arrows at the far right of the field, reminiscent of the controls on a vertical scroll bar, allow you to increment or decrement the value in the field.

The CheckList control is the same as that used when selecting what metadata sets to include in a new collection. After you have enabled it by clicking on the checkbox next to the argument's name, you select the active values by checking the checkbox next to them. The list is scrollable because there may be many entries to review. Note that the selection highlight has no real effect other than indicating the last entry whose state you changed.
