I would like to format a Microsoft Word document such that the first line of every paragraph is indented, with the exception of the first paragraph in a section which would not be indented. How can I do this?
You'll have to use two styles for this. For example you could change the "standard" style adding an indentation for the first line as described in the Microsoft Office Online help. Basically you'll have to go in "Indents and Spacing" and under "Indentation" click "First line" from the Special list. In the "By" box, set the amount of indentation.
Then, create a new style a name it "Paragraph1" for example. Remove the indentation from this style and apply it to every first paragraph of each section.
