This is generally a message planted in the center of the screen and usually contains some suggested responses. Almost always, one of the responses included the option OK , found in a rounded rectangle. You already saw a dialog when you saved a file at the beginning of this course. These rounded rectangles are often referred to as buttons , but should not be confused with the mouse button when instructions are given. When we say to click in the OK button , we mean that the mouse should be positioned so that the pointer is located in the area of the OK within the round rectangle and at that place, the mouse button should be pressed and released.
Many dialogs require more information than a simple OK response.
These have text areas that need to be filled in or changed. Sometimes there are also check boxes that can be set to specify options. Whenever you are faced with a dialog, you must respond to it before you can continue with your work. Choose Quit from the File menu. Click on the Cancel button.
