THE FORMAT BAR
The format bar runs horizontally just below the toolbar and allows you to access common formatting commands easily. From the format bar you can change the font, text alignment, line spacing, text and highlight colour, and create lists. You can turn the format bar on or off by choosing “Hide Format Bar” from the Format menu. Note that if you click the text colour or highlight buttons in the format bar, a menu will appear that allows you to choose from a list of colours (clicking on the buttons applies the currently-selected colour). You can customise what appears in the format bar with the Tools > Customize Toolbars… menu command.

THE FORMAT MENU
The Format menu provides various ways of formatting your text which are standard in many applications along with some that are unique to Scrivener, the latter of which are listed below.

HIGHLIGHT
Pretty straightforward, this one. Choose from several standard highlighter pen colours to highlight your text. 

INLINE ANNOTATION AND FOOTNOTES
 Inline annotations and footnotes allow you to make notes right inside your text (whereas inspector comments and footnotes are hidden away in the inspector until you need them—these will be available in the 1.1 release). Inline footnotes and annotations look like this:
This text has a footnote after it.{\Scrv_fn= This is a footnote.\end_Scrv_fn} When the text is compiled, exported or printed, this footnote will be turned into a “real” footnote (or endnote).
{\Scrv_annot \color={\R=1.000000\G=0.000000\B=0.000000} \text=And this is an annotation. Annotations can be completely removed from the text when you compile, print or export.\end_Scrv_annot}
Each was created by selecting the text and choosing either “Inline Annotation” or “Inline Footnote” from the Format menu. Alternatively, you can also just choose “Inline Annotation” or “Inline Footnote” with no selection and start typing (note that you can change the colour of an annotation in the Appearance tab of Options). When you export your work, ranges of text defined as footnotes can be turned into real RTF footnotes that can be read by Word, OpenOffice.org, WordPerfect and other major word processors. Ranges of text defined as annotations can be turned into RTF comments (which Word can read) or omitted altogether. One thing to note is that when you create inline footnotes, the grey bubble should start exactly where you want the footnote marker to appear in the printed or exported text.

SCRIVENER LINKS
Scrivener links are much like web hyperlinks, except that they link to other documents within the current Scrivener project. To create a Scrivener link, select the name of the document to which you wish to make a link from the Scrivener Links menu in the Edit menu. This will create a hyperlink in your text document. Alternatively, choose “New Link…” to bring up a sheet that allows you to create a new document to which to link, or to choose from existing documents in the project. Clicking on a Scrivener link will open the linked document in a split pane. Scrivener links can be useful for creating tables of contents or references within your research.

A PDF document will be opened in a new pane. Close the split pane and then move on to “Step 19” in the binder.
