What happens when you press the letter "G"?

Well if you chatting with someone, on Facebook, telegram, email, or whatever, when you press the letter "G", you type the letter to complete or to start a word like: I "got" new "glasses".

And if you are in the search bar of your browser, if hit the letter G and press enter, the search engine will search through the internet for the query you just entered.

Also if you are on a program, like Photoshop, or VS Code, a program where you can make a custom keyboard binding, you can set the letter G to be a function, so whenever you press G, something will happen, just like when you press Ctrl + S to save the file, or Ctrl + C to copy some text. and of course, you can tell the program what to do when you press G.
