This type is for regular paragraphs of text. The font again depends on the master template. This style is default for text when you add a label with text to the canvas.
Next to the paragraph are the list options, modeler supports ordered and unordered lists indented with numbers or bullet-points. Indentation can also be done here with a indent and a outdent button you can go as far as you want. The indenting happens per paragraph and does not have to be in a new label or text block for different indentations.
