There are several different keyboard layouts out there that come with different keys on them, depending on the layout. This is the reason when you install a new operating system, the setup process asks for the keyboard layout.
While most of the popular keyboards come with a US Keyboard layout, there are some layouts that include a Alt Gr or Alt Graph key. Some keyboards come with dedicated keys for currency symbols, special symbols, etc.
There is usually no option to disable the Alt Gr key on the keyboard but some workarounds are available. In this guide, we will show you how to remap the Alt Gr key to function as a normal Alt key on your keyboard. Do note that this guide is for the Windows operating system only.
