What is a simple guideline for developing Web pages to improve accessibility for users who have trouble using the mouse?

The guideline of ensuring that pages allow users to tab to new links is crucial for improving accessibility, especially for individuals who may have difficulties using a mouse due to mobility impairments or other reasons. This approach enables users to navigate through the website using the keyboard's tab key, which is an essential function for those relying on keyboard navigation rather than a pointing device.

By implementing this guideline, web developers can create a more inclusive environment that accommodates various users, including those who may use screen readers or alternative input devices. Ensuring that all interactive elements, such as links and buttons, are accessible via keyboard navigation allows these users to engage with the content effectively.

Other options, while beneficial to accessibility, do not directly address the specific need for mouse alternative navigation as directly as the ability to tab to links does. Providing shortcuts for keyboard navigation enhances usability but does not ensure all functional elements are accessible without a mouse. Ensuring graphics have captions aids users with visual impairments but is not focused on those who can’t use a mouse. Using color contrast helps users with visual challenges, but again, it does not directly assist those who are navigating without a mouse. Thus, facilitating tab navigation is the most straightforward way to improve accessibility for those unable to use a mouse.
