Info Keyboard, touch and accessibility

Keyboard, touch and accessibility

The shortcuts, gestures and reading controls that are easy to miss.

The site is usable with a keyboard, a mouse and a touch screen. These are the interactions that are not obvious from the layout.

Search

Control	Where	What it does
`/`	Content pages with a header search	Focuses the search box.
`↑` / `↓`	Search suggestions	Moves through the suggestions.
`Enter`	Search suggestions	Opens the highlighted suggestion, or submits the query.
`Escape`	Search suggestions	Closes the suggestion list.

Preview cards

Hover a link to open its card; move away to close it.
Escape closes the stack.
Click the pin in a card to keep it open.
On a touch screen, tap once to preview and tap again to follow the link.
Scroll near the bottom of a card to load the next chunk.

Graph and map

Wheel or pinch to zoom; drag to pan.
Use − and + to change the node budget.
On the map, click a country to open its corpus; zoom is the way to separate overlapping regions.
The International institutions tab lists regions without a country outline (currently the EU).

Reading

Click a heading to collapse or expand its block. The chevron button does the same and is easier to hit.
The table-of-contents jump box accepts section numbers, paragraph numbers and, for paginated U.S. cases, page numbers.
Deep links expand collapsed ancestors before scrolling, so a citation always lands on visible text.
The browser's own find function searches the whole instrument or judgment page, including collapsed text while it is expanded.

Accessibility

Pages use semantic landmarks and labelled navigation, links carry titles or aria-label text where the visible text is short, and the graph has a text fallback. Reference links are ordinary anchors, so they can be opened in a new tab, copied or followed with the keyboard. If a surface is hard to use with your assistive technology, the Info guide is the place to record the workaround until it is fixed.
