mxEvent.addListener(text, 'keydown', function (evt)
{
if (!(evt.keyCode &gt;= 48 &amp;&amp; evt.keyCode &lt;= 57) &amp;&amp;

{
mxEvent.consume(evt);
}
});</pre></blockquote><h4 class=CHeading>Placeholder</h4><p>To implement a placeholder for cells without a label, use the <a href="#mxCellEditor.emptyLabelText" class=LVariable id=link63 onMouseOver="ShowTip(event, 'tt11', 'link63')" onMouseOut="HideTip('tt11')">emptyLabelText</a> variable.</p><h4 class=CHeading>Resize in Chrome</h4><p>Resize of the textarea is disabled by default.&nbsp; If you want to enable this feature extend <a href="#mxCellEditor.init" class=LFunction id=link64 onMouseOver="ShowTip(event, 'tt22', 'link64')" onMouseOut="HideTip('tt22')">init</a> and set this.textarea.style.resize = &lsquo;&rsquo;.</p><p>To start editing on a key press event, the container of the graph should have focus or a focusable parent should be used to add the key press handler as follows.</p><blockquote><pre class="prettyprint">mxEvent.addListener(graph.container, 'keypress', mxUtils.bind(this, function(evt)
{
if (!graph.isEditing() &amp;&amp; !graph.isSelectionEmpty() &amp;&amp; evt.which !== 0 &amp;&amp;

{
graph.startEditing();
if (mxClient.IS_FF)
{
graph.cellEditor.textarea.value = String.fromCharCode(evt.which);
}
}
}));</pre></blockquote><p>To allow focus for a DIV, and hence to receive key press events, some browsers require it to have a valid tabindex attribute.&nbsp; In this case the following code may be used to keep the container focused.</p><blockquote><pre class="prettyprint">var graphFireMouseEvent = graph.fireMouseEvent;
graph.fireMouseEvent = function(evtName, me, sender)
{
if (evtName == mxEvent.MOUSE_DOWN)
{
