Focus and keys

Form in transform mode

Press Tab: focus moves through fields outside the visible area and content follows it. A press on a field focuses it instead of dragging while inputsFocus is on. Arrow keys inside a field move the caret, outside of fields they scroll.

Keyboard without focusable content

The viewport itself is focusable: tabindex="0" and a name in aria-label. Click it or Tab to it, then use arrows, Page Up, Page Down, Space, Home and End. With direction: 'horizontal' page keys, Home and End scroll horizontally. A key that content cannot take scrolls the page.

With textSelection a mouse press on text selects it and a press between paragraphs drags. On a phone a swipe drags from anywhere and a long press selects a word.
