The mouse wheel button in the win7 system is wonderful

Now, most of the mouse has a pulley, I believe everyone should be familiar with this, but for the wheel button, the function of pressing the wheel vertically, many people should I know very little about it. Below I will summarize the quick application of several pulley keys in the win7 system. 1. Automatic scrolling Click the wheel button at any position of the window to call up a two-way (or four-way) arrow. You can control the scrolling up and down (left and right) by moving the cursor, which is very convenient. This function is also present in the previous system, and it is not unfamiliar to everyone. 2, open the page in the background tab, I believe that everyone has had a similar experience, sometimes want to open a large number of web pages in the background tab, but every point to open a title to switch to the original web page is really annoying, now, Just click on the connection you want to open with the wheel button, you can automatically open the page in the background tab, eliminating the cumbersome switch back and forth. 3, open /close the program on the task bar In daily use, you will often need to open a program that has been opened (now displayed in the task bar), and win7 will select the program that should be opened by default. Use the wheel button to quickly launch the program. At the same time, if you use the wheel button to click the preview window of the program, it will quickly close the window, eliminating the trouble of finding a small fork. 4. Closing the tab page When you browse the webpage frequently, you often have to close the tab that has already been read. The commonly used chrome does not have the function of double-clicking off by default. It can only find the little red cross. It is often unsatisfactory. It is very uncomfortable to use the pulley button to click anywhere on the tab page. Br>
