Where is R1 key in computer keyboards?

The R1 key is not a standard key on most computer keyboards. Instead, it is often used in specific contexts, such as gaming or certain software applications, to refer to a button mapped to the R1 function, typically found on game controllers. If referring to a keyboard layout, the closest equivalent would be the "R" key, which is located on the right side of the home row, between the "E" and "T" keys.
