## Formula Fonts

You can define fonts for the variables, functions, numbers and inserted text that form the elements of your formula.

The list boxes in the \<emph\>Fonts\</emph\> dialog display a default font for all elements. To change to a different font, click \<emph\>Modify\</emph\>, then select the element type. A new dialog box appears. Select the desired font and check any desired attributes, then click \<emph\>OK\</emph\>. To set the changes as the default fonts, click the \<emph\>Default\</emph\> button.

If you want to mark individual text segments with a font other than that used for the whole text, then enter the Font command in the Commands window.

### Variables

You can select the fonts for the variables in your formula. For example, in the formula x=SIN(y), x and y are variables, and will reflect the assigned font.

### Functions

Select the fonts for names and properties of functions. For example, the functions in the formula x=SIN(y) are =SIN( ).

### Numbers

You can select the fonts for the numbers in your formula.

### Text

Define the fonts for the text in your formula here.

## Custom Fonts

In this section of the \<emph\>Fonts\</emph\> dialog you can define fonts, with which you can format other text components in the formula. The three basic fonts \<emph\>Serif, Sans\</emph\> and \<emph\>Fixed\</emph\> are available. You can add any other font to each standard installed basic font. Every font installed on your system is available for you to use. Select the \<emph\>Modify\</emph\> button to expand the selection offered in the list box.

These custom fonts are used if you set a different font with the FONT command in the \<emph\>Commands\</emph\> window.

### Serif

You can specify the font to be used for the font serif format. Serifs are the small "guides" that can be seen, for example, at the bottom of a capital A when the Times serif font is used. Using serifs is quite helpful since it guides a reader's eye in a straight line and can speed up reading.

### Sans

You can specify the font to be used for sans font formatting.

### Fixed

You can specify the font to be used for fixed font formatting.

## Modify

Click one of the choices from this pop-up menu to access the Fonts dialog, where you can define the font and attributes for the respective formula and for custom fonts.

## Default

Click this button to save your changes as the default for all new formulas. After confirming the changes, click the Yes button.
