What is the scroll wheel in the middle of the mouse

The mouse wheel is a ball at the bottom of a mechanical mouse that can be rolled freely. When browsing web pages or files, scroll forward or backward by turning the scroll wheel.

The following are several shortcut applications of the mouse wheel key:

1. Implement page turning function

When we are browsing the web, we only need to slide the mouse wheel with our fingers to easily flip the web page up and down without moving the mouse or clicking the scroll bar. This operation method is very intuitive and easy to use. Therefore, the mouse wheel is praised as a highlight of Internet mice. In addition, in many editing windows and browsing windows, such as Microsoft Office and other applications, the scroll wheel key can also conveniently replace the scroll bar to achieve the up and down flip function. This feature is particularly useful for browsing and editing large documents.

2. Realize picture frame flipping

In ACDSee, when opening multiple image files, you usually use the "Previous" and "Next" buttons in the "Tools" bar to flip the pictures. However, what is less known is that you can also use the mouse wheel to easily flip through pictures, even including all other unopened pictures in the folder where the opened picture is located. This feature can improve your efficiency when working with images, allowing you to browse and edit pictures faster. Now, you can try using the mouse wheel to easily flip pictures and enjoy a more convenient operating experience.

3. Let the screen scroll automatically

In many editing windows, such as in Word, pressing the mouse wheel key will display a black up and down two-way arrow. Move the mouse pointer below the double-headed arrow and the screen will automatically scroll up. The further you move the mouse pointer away from the two-way arrow, the faster the screen will scroll. To scroll up the screen, simply move your mouse pointer over the two-way arrow.

4. Quickly get the best view

In addition to being able to turn pages, the scroll wheel mouse also has another important function when pressing the Ctrl key, that is, it can easily zoom the display content of many windows to obtain the best view.

5. Press the mouse wheel on a link in IE8 to open a new tab.

How to set the mouse color in excel table

1. Scroll the table up and down: In the excel worksheet, select a cell, and then roll the wheel up and down, the table will scroll up and down. This is similar to clicking the up and down arrows of a scroll bar. But clicking the up and down arrows of the scroll bar can only scroll one line at a time, while rolling the mouse wheel can scroll one or more lines. In Windows XP or Windows Vista, the number of lines per scroll can be set in the control panel. Taking Vista as an example, the method is: click "Start → Control Panel → Mouse", the "Mouse Properties" dialog box will pop up, select the "Wheel" tab, and in the "Vertical Scroll" area, select "Scroll the following number of lines at a time" , and set the desired quantity. If you select "Scroll one screen at a time", each time you scroll the wheel, the Excel table will scroll the number of rows displayed on the screen, which is equivalent to pressing the pageup or pagedown key. This method also applies to word or browsing the web in a browser.

2. Scroll the table left and right: Press the scroll wheel in the table and the mouse will change into the shape below. Then drag the mouse left and right to scroll the table left and right. If you drag the mouse up and down, you can also scroll the table up and down. The farther the mouse is from where it was pressed, the faster the scrolling speed will be. Pressing the mouse again or rolling the wheel cancels this scrolling.
