Toolbars

A toolbar provides a quick access to the most frequently used actions performed using the menu. A toolbar offers these items as buttons. For WordPad, the top toolbar is called the Standard toolbar:

Each toolbar button is used to perform a different and particular action. When you position the mouse on top of a button, a tool tip appears, letting you know what the button is used for.
WordPad is equipped with a second toolbar called the Formatting toolbar. Besides the usual buttons, a toolbar can offer many other windows controls, some of which we will explorer later.

Status Bars

The Status Bar helps as a guide to the users of an application. In a typical application, it displays small sentences that further explain the role of a particular button or an action that you are about to perform. The messages that appear on the Status Bar vary from one application to another and depend on the position of the mouse on an application. At this time, you should still have the Control Panel application running.
The Single Document Interface

WordPad is a Single Document Interface application, which means it allows you to work on only one opened document at a time. On top of most or all of Windows applications, there is the title bar:

On the left side of the title bar, there is an icon that identifies the application you are using. This icon is called the system icon. Every application that looks like WordPad is equipped with this type of icon but the icons are different from one application to another. This is because the person who creates the application also designs the icon that goes with it. The system has its own menu called the system menu. To access this menu, simply click the system icon.
On the right side of the icon, the name of the file is followed by the name of the application you are using, in this case WordPad. This sequence is not the same on all applications. Again, it depends on the application and how the programmer decided to make it appear.
