Which finger is responsible for typing the letter 'R'?

The correct answer is that the left index finger is responsible for typing the letter 'R'. In touch typing, each finger is assigned specific keys on the keyboard to promote efficiency and accuracy. The left index finger is positioned to cover the keys on the left side of the keyboard, which includes the letter 'R' located in the middle of the top row of keys.

By using the left index finger for this key, typists can maintain proper hand position, allowing for quicker movement to adjacent keys without excessive hand motion. This practice is essential for developing good typing habits and increasing overall typing speed.

Each finger has a designated area of the keyboard to stay within, enhancing muscle memory and reducing the likelihood of mistakes. This method of finger placement and key responsibility is a fundamental principle in touch typing.
