You can apply formatting (styling attributes) to a whole block of text or to individual characters in a text block.
To format one or more characters in a text block
In the Toolbox, select the Text tool.
Drag the Text tool over the text to select the text you want to format.
In the Properties panel, in the Text category, make the following changes:
Font Select a font in the Font gallery.
Size In the Type Size list, select a text size, or click the field to type a specific size. By default, text size is specified in points (1/72 of an inch).
To change the way text size is specified, on the Edit menu, point to Options, and then click Units and Grids. On the Units and Grids pane, under Units, in the Type units list, select the measuring units you prefer.
Color and stroke Each character in a block of text is considered a separate object and can have its own fill and stroke settings. Change these settings in the Properties panel, in the Appearance category. For more information, see Using fills and strokes.
Alignment While all the previous formatting can apply to individual characters, the horizontal alignment formatting always applies to a whole block of text. For ordinary text and text on a path, you can select from among the Left, Center, and Right alignment buttons. For area text, you can also select the Justify or Justify All options. (Justify All is also named force justified.)
Leading Controls the amount of vertical space between lines in a text block. By default, Microsoft Expression Design applies an automatic amount of leading between lines. Change this setting in the Leading list in the Text category. Leading is set as a percentage of font size. Click the field to type your own percentage value. You can change the leading of selected characters, but Expression Design applies the leading value of the last character in each line of text to the whole line.
Tracking Controls the horizontal space between individual characters. In the Text category, in the Tracking list, change the tracking of one or more characters. A positive tracking value adds space to the right of each selected character. A negative value removes space. This makes the spacing tighter. If you want to adjust the spacing between two adjacent characters (also named kerning), select only the first character of the pair and apply tracking to it. Double-click the Tracking field to type your own setting.
Horizontal scaling Change how wide each character appears by adjusting the Horizontal Scale. The space between the characters is also scaled.
Base line offset Use the Base line offset control to move one or more characters up or down from their usual baseline.
Super/Subscript Click either the Superscript or Subscript button to change the baseline shift and size of selected text. To remove this formatting, select the text, and then click Normal.
If you want to change all the text blocks in your document to a different font, first select one text block with the Selection tool and then use the Select by feature (on the Select menu) to select all the other text blocks that use the same font. Then you can change the font under Text in the Properties panel and all the selected text blocks will change. For more information, see Select objects using shared attributes.
