# Accessibility Every control has a native label and every operation is available without precision pointer input. The four graphical corner handles are focusable sliders: arrow keys move by 0.2 percent and Shift+arrow moves by 1 percent. Their values are announced as horizontal and vertical percentages. Source and processed views have accessible names, while status, errors and OCR progress use live native semantics. Page cards are clickable and preserve document order; drag and drop is a convenience rather than a prerequisite because files can be added in order and removed individually. Controls retain visible focus. Layouts collapse into document order on narrow screens, large hit areas are used, colour is never the only status cue, and reduced-motion plus shared system/light/dark themes are supported.
