The Menu bar can be used to start an operation, to create or edit objects, to view the properties of an object, etc.
The Standard toolbar provides shortcuts for regularly used menu commands such as Customize Catalog, List/Details View, etc.
Object selection Toolbar:
The Object selection toolbar can be used to select the object types that should be visible in the currently active Catalog.
The Command line is mainly used to type calculations (MapCalc) and expressions (perform operations).
Operation-tree and Operation-list:
The Operation-tree provides a tree structure for all operations, similar to the Operations menu.
The Operation-list contains an alphabetic list of all operations. Each operation is preceded by an icon; the icon indicates the output data type of the operation.
You can use the Navigator to change the current drive and working directory. Click the word Navigator in the Operations/Navigator pane
The Navigator lists all drives and directories (folders) in a tree structure. It also has a History to easily return to previously visited drives and directories.
Click on the drives and folders in the Navigator until you are in the directory where the data for these exercises has been stored.
This part of the Main window, in which maps, tables and other objects in the working directory are displayed, each with its own type of icon, is called the Catalog. When you double-click an object in the Catalog, it will be displayed.
The Map viewer helps you to show all the data maps, chart, layout.
The Status bar gives short information on the item on which the mouse pointer is located: a menu command, a button in the toolbar, an object in the Catalog, an operation in the Operation-list or the Operation-tree, etc.
