Is there a key to explain what all the abbreviations mean or a version with a live preview? The balloon texts are not really self-explanatory. Even just a text list of all the commands and their functions would be helpful. For example, I don't understand the difference between "background", "background_gui" and "w_background_base". By hovering over each option, I get balloon tips which say "selects a background", "select a stretchable background" and "select a cropped background" so it's gonna take a lot of trial and error to by swapping out my SD card, editing some changes and then re-booting the Wii to see which changes have taken effect.
