If your text is left-justified, the extra indentation will be on the left; if your text is right-justified, the extra justification will be on the right; if your text is centered, extra indentation doesn't apply and these controls will be disabled.
1st Line (cm): Lets you specify, in centimeters, extra indentation for the first line of every paragraph.
Other Lines (cm): Lets you specify, in centimeters, extra indentation for all non-first lines of paragraphs.
