Generally, it is combined with other keys to achieve a variety of special fast functions. The specific functions will be described in detail in the Alt key functions below. .

Without a mouse, you can use the Alt key to open the menu of the software. In the computer keyboard, there are two Alt keys on the keyboard, one left and one right. In an American keyboard, the keys on the left and right are used for the same purpose. But you know what? On most European keyboards, the alt key on the right is labeled Al + Gr, which works much like the shift key-press both the conversion key and the letter key to choose uppercase or lowercase.
