What purpose do shift locks serve in typing?

Shift locks serve the primary purpose of allowing typists to type multiple uppercase letters without needing to hold down the Shift key for each individual character. When the Shift lock is activated, it maintains the uppercase setting for subsequent letters until it is toggled off, enabling smoother typing and reducing finger strain. This feature is particularly beneficial for typing extended sections of capital letters, such as in acronyms or headings, improving typing efficiency.

The other options, while they have their own functionalities, do not accurately reflect the specific role of shift locks. Some options may involve different keyboard functionalities or settings, but they do not relate directly to the function of maintaining a shift state for uppercase letters.
