Me again. Two posts and i'm a total noob (to the forum not word)

i though i may as well ask this while i am here.

When i started my PhD four years ago i had a workshop on how to use styles for headers etc to generate a content page automatically. Do you think i can find my notes. no. no i can't find my notes.

Does anyone have a link to a tutorial that shows hoe to do this. will have a look but i thought maybe someone will have a link handy as i guess you are all much more advanced word users than me.

many thanks.
