The current selection is rendered by executing browser command read-current. The rendering commenced by read-current can be interrupted in two ways:
Another browser action is to render the rest of the document starting from the current selection. This is enabled by browser command read-rest (bound to c).
Moving the selection to the next or previous node and then rendering is a common sequence of actions. AsTeR provides commands read-previous and read-next (bound to p and n respectively) that combine these actions.
In addition, the browser provides command read-just-this-node (bound to r) that renders only the current node, rather than the entire subtree rooted at this node -this is useful when traversing complex mathematical expressions.
