What is the primary reason for ensuring actions can be easily performed with a keyboard?

The primary reason for ensuring actions can be easily performed with a keyboard is to accommodate users who cannot use a mouse due to physical disabilities. Many individuals rely on keyboard navigation as their sole means of interacting with digital content because they may have conditions that impair their ability to use a mouse effectively. By allowing keyboard interactions, designers ensure that these users have equal access to the functionalities of a website or application, which fosters inclusivity and accessibility.

This consideration is essential in creating an accessible environment that supports diverse user needs, ensuring that all individuals can perform necessary actions without barriers. Keyboard accessibility is a fundamental aspect of web development and design that adheres to accessibility standards such as the Web Content Accessibility Guidelines (WCAG).
