All of the controls you need to use X-Author Designer are located in the X-Author Designer ribbon menu in Microsoft Excel.

Before you start designing apps, you should familiarize yourself with the X-Author for Excel components that are accessed through the X-Author Designer ribbon menu. Click the link in the first column to learn more about the component. 

AppsClick this button to create a new app, change the app type, or open an existing app. (Click the Quick App button to instead create a simple single-object app or a parent-child-type app.)

Display MapClick this button to define the associations between Excel spreadsheet cells and fields for the environment data to be retrieved. When data is retrieved, using one of the X-Author data invoking actions, it is temporarily stored in Excel memory before being placed into the worksheet. X-Author then uses a Display Map to place the data in the correct Excel cells.
Matrix MapClick this button to define a matrix map. Matrix maps extend the capabilities of X-Author for Excel well beyond list formats. In lists, one record is represented per Excel row or column. Using matrices, a record can be represented by one or more cells by mapping columns and rows (the X and Y axes) of a matrix as well as the data contained in the cell at the intersection of the mapped column and row. Depending on the type of matrix, various data cells can be updated by a user. If no value exists in a cell, adding a value can create a new record depending on the matrix design.
Save Map

Click this button to define relationships between fields and Excel cells for data that will be saved to your environment.
