Keyboard Accessibility

Vesper Inspect surfaces keyboard accessibility information directly in the hover tooltip as you inspect elements. This lets you spot keyboard focus and reachability problems without running a separate scan or switching to a browser DevTools panel.

Tab order and keyboard reachability

For every element you hover, the tooltip shows whether it is reachable by keyboard:

• A green pass indicator means the element is in the tab sequence and will receive focus when the user presses Tab.
• A red fail indicator means the element is not keyboard reachable.

Ancestor context is included. If you hover an image that is a child of a link, the tooltip reports the keyboard reachability of the link - the element that actually receives focus.

Tabindex

When an element has an explicit tabindex attribute, the tooltip shows its value:

• tabindex="0" - The element is included in the natural tab sequence.
• tabindex="-1" - The element can receive focus programmatically (via script) but is not reachable by pressing Tab.
• A positive tabindex - The element is given a custom position in the tab order. Positive tabindex values override the natural DOM sequence and are generally discouraged.

Heading level and skip detection

Heading elements (<h1> through <h6>) show their explicit level in the Role row. If a heading skips a level relative to the previous heading on the page - for example an <h4> immediately following an <h2> - the row is flagged red. Heading level skips break the logical document outline and create a confusing experience for screen reader users who navigate by heading.

Link destination

For anchor elements, the tooltip shows the raw href value. This lets you confirm where a link actually goes without leaving the page - useful when link text alone is ambiguous or when checking that visually identical links point to different destinations.

aria-hidden on interactive elements

When an element has aria-hidden="true" (or is inside an ancestor with aria-hidden="true") and is also keyboard-focusable, the tooltip flags it as a red error. A sighted keyboard user can reach and activate the element, but a screen reader user will hear nothing announced when it receives focus.

Keyboard shortcut

You can toggle Vesper Inspect on and off with Option+Shift+I on macOS without clicking the toolbar icon. The shortcut can be reassigned at chrome://extensions/shortcuts.
