    <p>Ok so, what I need to do is change some numbers on the screen when keys are pressed, i have it working but I'm not happy with it. </p> <p>I have a input field and a div that is being updated when the value of the input filed changes. I did that so that I would not be constrained by the input field's blinking carat etc. I don't want to display the input field at all but when I hide it with CSS or type="hidden" it no longer works. I was trying to get this working with JS variables but so far have been unsuccessful. </p> <p>Any ideas? </p> <p>HTML</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;link rel="stylesheet" type="text/css" href="number.css" /&gt; &lt;/head&gt; &lt;body onLoad="focus();myText.focus();changeNumber()"&gt; &lt;div id='number'&gt; &lt;/div&gt; &lt;input type="text" id="myText" value="1"/&gt; &lt;/body&gt; &lt;footer&gt; &lt;script type="text/javascript" src="number.js"&gt;&lt;/script&gt; &lt;/footer&gt; &lt;/html&gt; </code></pre> <p>JAVASCRIPT</p> <pre><code>var myText = document.getElementById("myText"); function changeNumber(){ var userInput = document.getElementById('myText').value; document.getElementById('number').innerHTML = userInput; } // Capture keyDown events myText.onkeydown = function(e) { // "34" is the up arrow key if (e.keyCode == 34) { // increment the value in the text input myText.value++; changeNumber() // "33" is the down arrow key } else if (e.keyCode == 33 &amp;&amp; myText.value &gt; 1) { // decrement the value in the text input myText.value--; changeNumber() } } </code></pre> <p>HERE IN THE FINAL FIXED CODE <strong>* THANKS GUYS! **</strong></p> <p>HTML</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;link rel="stylesheet" type="text/css" href="number.css" /&gt; &lt;/head&gt; &lt;body onLoad="focus();number.focus();changeNumber()"&gt; &lt;div id='number' value="1"&gt; &lt;/div&gt; &lt;/body&gt; &lt;footer&gt; &lt;script type="text/javascript" src="number.js"&gt;&lt;/script&gt; &lt;/footer&gt; &lt;/html&gt; </code></pre> <p>JAVASCRIPT</p> <pre><code>var i = parseInt(1); function changeNumber(){ var userInput = i; document.getElementById('number').innerHTML = userInput; } // Capture keyDown events for document document.onkeydown = function(e) { // "34" is the PGUp key if (e.keyCode == 34) { // increment the value in the text input (i++); changeNumber() // "33" is the PGDown key } else if (e.keyCode == 33 &amp;&amp; i &gt; 1) { // decrement the value in the text input (i--); changeNumber() } // "66" is the b key if (e.keyCode == 66){ window.location.reload() } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
