<h3>Module: node-focusmanager
</h3>
<div class="description summary">
<p>The Focus Manager Node Plugin makes it easy to manage focus among
a Node's descendants. Primarily intended to help with widget development,
the Focus Manager Node Plugin can be used to improve the keyboard
accessibility of widgets.</p>
<p>
When designing widgets that manage a set of descendant controls (i.e. buttons
in a toolbar, tabs in a tablist, menuitems in a menu, etc.) it is important to
limit the number of descendants in the browser's default tab flow. The fewer
number of descendants in the default tab flow, the easier it is for keyboard
users to navigate between widgets by pressing the tab key. When a widget has
focus it should provide a set of shortcut keys (typically the arrow keys)
to move focus among its descendants.
</p>
<p>
To this end, the Focus Manager Node Plugin makes it easy to define a Node's
focusable descendants, define which descendant should be in the default tab
flow, and define the keys that move focus among each descendant.
Additionally, as the CSS
<a href="http://www.w3.org/TR/CSS21/selector.html#x38"><code>:focus</code></a>
pseudo class is not supported on all elements in all
<a href="http://developer.yahoo.com/yui/articles/gbs/">A-Grade browsers</a>,
the Focus Manager Node Plugin provides an easy, cross-browser means of
styling focus.
