How to use the ctrl key

1. When browsing the web with IE, there is a "magnifying glass" at the bottom right of IE, and you can click the icon to adjust the size of the web page. But we can also press "Ctrl++" or "Ctrl+-" to zoom in on the page, the latter to zoom out on the page, and the "+" and "-" keys on the keypad can also be selected, especially this operation only zooms in on the content of the current page, not the entire page. Using Ctrl + Mouse Wheel also has the same feature and is more convenient.

2. When moving a folder, if you move it directly, it will move the original folder to another place. But sometimes we want to move files and keep them at the same time. Just press Ctrl and move it again, and it will be copied to another folder.

3. When using the keypad to simulate the mouse operation, you can use the number keys (except 5) to move the mouse in all directions, hold down the Ctrl key to speed up, and hold down the Shift key to slow down.

4. After clicking the desktop with the left mouse button, press CTRL+mouse wheel to see what will appear, and whether the desktop icon is enlarged or reduced at will.
