AltGr key
The altgr key is a special key on your computer keyboard that you can press to do different things. Sometimes the keyboard doesn't have enough space for all the keys, like if you have a lot of different symbols or letters that aren't used very often. Altgr helps to fix this problem by being an extra key that you can use to get to some of these symbols or letters.
For example, if you need to type a funny letter like the "é" in "café," you can press and hold the altgr key and then press the key for the letter "e" at the same time, and voila! You have your funny letter.
Some languages have even more special symbols and letters that they need to use. By using the altgr key and combining it with other letters or symbols, you can access all these special characters easily. So, it's like a secret keyboard shortcut that makes typing in different languages or including special characters a piece of cake.
