    <p>I'd suggest:</p> <pre><code>function idProgress (e) { var self = this, id = self.id, next = self.nextElementSibling; if (next === null) { // this assumes you don't want to remove the last element return false; } else { self.parentNode.removeChild(self); next.id = id; next.addEventListener(e.type, idProgress); } } var span = document.getElementById('current'); span.addEventListener('click', idProgress); </code></pre> <p><a href="http://jsfiddle.net/davidThomas/R4SMM/" rel="nofollow">JS Fiddle demo</a>.</p> <p>To remove all the <code>span</code> elements click-by-click (including the last):</p> <pre><code>function idProgress (e) { var self = this, id = self.id, next = self.nextElementSibling; self.parentNode.removeChild(self); if (next !== null) { next.id = id; next.addEventListener(e.type, idProgress); } } var span = document.getElementById('current'); span.addEventListener('click', idProgress); </code></pre> <p><a href="http://jsfiddle.net/davidThomas/R4SMM/4/" rel="nofollow">JS Fiddle demo</a>.</p> <p>To use <code>keypress</code> rather than <code>click</code> (which I overlooked on first reading the question):</p> <pre><code>function idProgress (e) { var self = this.getElementById('current'), id = self.id, next = self.nextElementSibling, key = e.which; if (key !== 110 || next === null) { return false; } else { self.parentNode.removeChild(self); next.id = id; } } document.addEventListener('keypress', idProgress); </code></pre> <p><a href="http://jsfiddle.net/davidThomas/R4SMM/2/" rel="nofollow">JS Fiddle demo</a>.</p> <p>Or:</p> <pre><code>function idProgress(e) { var self = this.getElementById('current'), id = self.id, next = self.nextElementSibling, key = e.which; if (key == 110) { self.parentNode.removeChild(self); if (next !== null) { next.id = id; } } } document.addEventListener('keypress', idProgress); </code></pre> <p><a href="http://jsfiddle.net/davidThomas/R4SMM/3/" rel="nofollow">JS Fiddle demo</a>.</p> <p>References:</p> <ul> <li><a href="https://developer.mozilla.org/es/docs/DOM/elemento.addEventListener" rel="nofollow"><code>element.addEventListener()</code></a>.</li> <li><a href="https://developer.mozilla.org/en-US/docs/Web/API/event.which?redirectlocale=en-US&amp;redirectslug=DOM%2Fevent.which" rel="nofollow"><code>event.which</code></a>.</li> <li><a href="https://developer.mozilla.org/en-US/docs/Web/API/ElementTraversal.nextElementSibling" rel="nofollow"><code>nextElementSibling</code></a>.</li> <li><a href="https://developer.mozilla.org/en-US/docs/Web/API/Node.parentNode" rel="nofollow"><code>parentNode</code></a>.</li> <li><a href="https://developer.mozilla.org/en-US/docs/Web/API/Node.removeChild" rel="nofollow"><code>removeChild()</code></a>.</li> </ul>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
