Ensuring reliable keyboard navigation and ARIA labeling in Insomnia’s request editor and response viewer

The goal is to make Insomnia’s request editor and response viewer fully accessible via keyboard navigation and screen readers, ensuring that each UI element is announced with purposeful ARIA labels and that focus moves predictably through the interface.

Because modifying ARIA attributes or altering the tab order could disrupt existing plugins or custom workflows that rely on the current DOM structure, any redesign must preserve backward compatibility, and color contrast adjustments must be validated for both light and dark themes to avoid creating new accessibility issues.

What is the minimal set of ARIA attributes required to accurately describe each input field? How should the tab order be restructured to follow a logical sequence (URL → method → headers → body → send)? Which accessibility audit criteria must be met before a change can be considered ready for release?
