What is a Window?
(Page 2 of 3)
Windows Navigation Buttons
At the upper right hand corner of most windows, you will see three small squares, called buttons, which always appear in the same order, as shown in Figure 6.
|
The 3 small squares are the navigational keys to managing a window
The button with a single horizontal line minimizes the window to the task bar at the bottom of the screen, effectively tidying up the screen somewhat. Minimizing an application also reduces the amount of work Windows allows the application to do. The button with a square maximizes the window, causing it to cover as much of the screen as it can. When clicked, it turns into the “Restore” button, which looks like two overlapping squares and when clicked returns the window to its original size and position. Finally, the “X” button closes the window and removes it from memory. If this is the last window open within an application, the application usually exits unless configured to do otherwise.
If you lose track of which button does what, you can move your mouse pointer over each button and hold it there for a few seconds. This will cause windows to display a “tooltip” describing that button’s function to jog your memory. Tool tips are included in most well written applications, and are a quick way to gain an understanding of what functions are available.
