Keyboard customization refers to the process of modifying a keyboard's layout, appearance, or functionality to better suit individual preferences or needs. This can include changing keycaps, adjusting key assignments, or using software to create macros that automate repetitive tasks. Many users opt for mechanical keyboards for customization due to their modular design, allowing for easy swapping of components. Additionally, gaming keyboards often come with built-in software that enables users to personalize lighting effects and key functions, enhancing both aesthetics and performance during use.
