Select a level (for example, "TOC 1" for the main Chapter headers) and click "Modify".Change the font here to match the font in the rest of your document.In most cases, you will probably need to create a customized Table of Contents by selecting "Custom Table of Contents". If you are creating a Table of Contents for a thesis or dissertation, there are several settings you will need to change.First, make sure "Show page numbers" and "Right align page numbers" are checked, and that the Tab leader is set to dots ("......") -- these settings will make sure you have dots between the chapter titles and page numbers, and that the page numbers are neatly aligned along the right margin.Next, on the "Home" tab on the menu, go to the Styles section and find the style "Heading 1" (but don't click it yet, because clicking it will reformat your title to Word's default "Heading 1" style format).For your first chapter heading, right-click the style "Heading 1" and select "Update Heading 1 to Match Selection".This will not print as part of your document; Word only uses it to identify it as a Table of Contents marker.You can change the text to be displayed in the Table of Contents by editing the text within the quotation marks inside the brackets.
Press "Alt-Shift-O" (letter O, not zero) to open a manual Table of Contents Entry box.
In the "Entry" field, enter the text for this section as you would like it to be displayed in your Table of Contents.
Next to "Level", select "1" for main chapter titles, "2" for subchapters, "3" for sub-subchapters, etc.
If you used styles other than "Heading 1", "Heading 2", and "Heading 3" to define your Table of Contents, you can also define those here.
When finished, click "OK" to return to the Table of Contents window. The Style window will open; this is where you can define the font and indents for each title level in the Table.
If your Table of Contents needs to be double-spaced, be sure to also click the double-spacing button.
