I think that is what they mean.
"voorstel" usually would be translated a proposal, but in computers a "proposal" is to be seen as a "proposed value", that is the default value which can be changed by the user.
"regel" is rtanslated either as "line" or "riule", whereby line does not make sense in computer programs in combnation with default.
