    space play / pause · ← → step · shift+arrows jump 100 · drag the timeline to move through time or click an event to jump to it · scroll on a tree to zoom, drag to pan, double-click to reset · hover over a node for its full condition. In the timeline, the grey area is tree size, the pink line counts the leaves that predict the alternation, and the ticks mark changes to the phonological grammar.
