Final answer:
Derek will find the bumps for hand placement on the c. F and J keys of the keyboard, which indicate where to place his index fingers for proper typing technique on the home row.
Step-by-step explanation:
When Derek is learning to type and focuses on proper hand placement, he can locate the raised bumps on the keyboard on the F and J keys. These tactile markers help typists correctly position their index fingers without looking at the keyboard, ensuring that they can maintain the correct hand positioning while typing. It's crucial for Derek to start with his index fingers on the F and J keys because this is the starting point for the home row, the row where typists are taught to keep their fingers anchored and from which they reach out to other keys.
When Derek sits down to start typing, the bumps that indicate where to place his index fingers can be found on the F and J keys. These keys are known as the home row keys and are specifically designed to help new typists locate the correct hand placement without looking at the keyboard. The F key on the left side of the home row is typically bumped so that the left index finger can easily find its position, and the J key on the right side of the home row is bumped for the right index finger.
