Some tips on the keys in the Win 7 system are two

Quickly open a window. Sometimes you need to open a new program window, such as a resource manager or a browser, etc. How do you do this? Generally we will find the program shortcut and then double-click the new window; Windows 7 more familiar friends may prefer to use shift + click on the taskbar program icon to open a new way. In fact, there is a more direct method —— directly use the middle mouse button to click the icon on the Windows 7 taskbar (as long as this program supports multiple processes running at the same time). Quickly close the middle button to click not only to quickly open a new window, but also to close the window quickly. After the Aero effect is turned on in the Windows 7 taskbar, after a program such as IE opens multiple tabs/windows, it can be used to view a thumbnail preview of each window. The user at the tip of the eye should notice that when the mouse moves to a thumbnail window, a small button similar to close will be displayed in the upper right corner. Clicking on it will close the window or tab (above). However, because this button is relatively small, it is not easy for small screen users to quickly locate. In fact, we don't have to go to the small button, just click the middle mouse button on the thumbnail to play the same role.

When a thumbnail preview has multiple windows or labels, the middle button clicks to close the specified window or label: if there is only one window, the entire program is closed (for QQ it seems that this method cannot be used to close the main program, only Close the chat window).
