Choose a Font Family, Style and Size using ADT's specialized pop up text fields (see User Interface). Enter your given Text and a stylized preview will be rendered in the Preview area.
Modify the "Target" area to have guides appear showing the various measurements you've entered such as height and width. The use of these guides is especially helpful for checking the point size needed for to meet legal requirements for printed materials (such as FDA requirements). Zoom in and out as you like using the combo box located at the bottom-left corner of the preview area.
This utility is also helpful when you need to quickly preview the appearance of type using different fonts for applications such as logotype and headlines. After entering the text you would like to have shown, click your cursor in either the "Font Family" or "Style" text fields and use the Up and Down arrows on your keyboard to quickly scan through fonts that are active on your system.
