Which typing technique helps improve speed without sacrificing accuracy?

Touch typing with all fingers is a technique that significantly enhances typing speed while maintaining accuracy. This method involves using all ten fingers on the keyboard, allowing for efficient movement and distribution of work across all fingers. This technique enables typists to develop muscle memory for key locations, which speeds up the process of typing as individuals do not need to visually search for keys.

Additionally, touch typing encourages a consistent rhythm and reduces the likelihood of errors since all fingers are engaged and can quickly reach the necessary keys. The more one practices touch typing, the more proficient one becomes, which leads to increased speed without sacrificing the precision that is often lost when using techniques like one-handed typing or looking at the keyboard.

This explanation illustrates the importance of touch typing in achieving a balance between speed and accuracy, making it the most effective approach among the choices provided.
