Regardless of whether you are filling out or designing a form, the Microsoft Office InfoPath 2003 workspace is divided into two main areas; the form area and the task pane area. The form area appears on the left side of the screen and the task pane area appears on the right.
The form area
The task pane area
By default, the task pane area is the area located to the right of the form area, but it can be repositioned, resized, or closed according to the user’s preference. Task panes (task pane: A window within an Office program that provides commonly used commands. Its location and small size allow you to use these commands while still working on your files.) typically contain commands for certain InfoPath features, such as spell checking, text formatting, and control insertion, but they can also contain instructional text, hyperlinks, or galleries for items such as clip art. Task panes can also contain form-specific content, such as command buttons and data catalogs. Task panes provide a simple way for users to complete tasks with their forms in full view.
