Full Keyboard Navigation Support

This question asks if someone can use every feature of your software using only a keyboard - no mouse required. Many users can't use a mouse due to vision impairments, motor disabilities, or assistive technology requirements. It's like asking if your entire product can be operated with just one tool that everyone can use, regardless of their physical abilities.

Keyboard accessibility is non-negotiable for enterprise sales and legal compliance. Without it, you exclude users with motor impairments, blind users, and power users who prefer keyboard shortcuts. This is often the first technical test in accessibility audits. Failing here means automatic rejection from government contracts, education deals, and Fortune 500 companies. Proper keyboard support also improves overall usability and productivity for all users.

Teams often test only the happy path, missing critical functions like closing modals, accessing dropdown menus, or navigating data tables. Another mistake is making keyboard navigation technically possible but practically unusable - requiring 50 tab presses to reach common functions. Don't forget about keyboard traps where users get stuck in elements like embedded videos or custom widgets.
