Aim
LatticeMLS uses headings, labeled controls, visible keyboard focus and text alongside status icons. This page describes the available features and known limitations. It makes no formal conformance claim.
Features
- Reading, the full topic list on the Search page and the lesson self-checks work without JavaScript.
- In Display, choose Day, Dusk or your system's theme, and set text size and density. You can also choose the Atkinson Hyperlegible Next legibility font.
- Motion follows your system's reduced-motion setting.
- A "Skip to content" link appears when you begin navigating with Tab.
- In Windows contrast themes, controls retain borders and selected choices have a visible outline.
- Lab stations open at every window size. On smaller screens and at higher zoom, the room and controls form a scrolling column.
- Drawn diagrams follow the theme. Teaching photographs sit on a neutral mat without color filters and open in an enlarged viewer.
Keyboard shortcuts
- / opens search from any reading page. You can turn off this shortcut under Display.
- Ctrl K or ⌘ K also opens search.
- Escape closes the menu, a pop-up or a dialog and returns focus to where you were.
- At the Dilution station, Enter or leaving a field commits an entry, and Escape leaves the focus view.
- The Microscope shows its counter shortcuts during counting. The Blood bank's antigram is one Tab stop, with arrow keys moving between cells and column headings.
Known limitations
- A screen reader announces a drawing as a whole through its description and caption. Individual labels inside the drawing may not be announced separately.
- Identifying cells at the Microscope is a visual task. Count photographs give the cell's position and call status without revealing its identity. The CBC, counter, morphology choices and report use text and labeled controls.
- Lesson photographs have descriptions and accompanying morphology criteria. These cannot fully convey the visual detail used to identify a cell.
- Search results need JavaScript. Without it, the Search page lists every topic in reading order and your browser's Find command searches it.
