Body
This is due to the character <code>3</code>'s <a href="http://en.wikipedia.org/wiki/ASCII" rel="nofollow">ASCII</a> value (ASCII is a widely-used way for computers to numerically represent various common characters). If you look under the <a href="http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters" rel="nofollow">ASCII printable characters</a> section of that Wikipedia article, you'll see that the Glyph (or character) <code>3</code> has a Dec value of <code>51</code>. You can see the dec values of other common printable characters in that same table. Remember that when you press the <kbd>3</kbd> key on your keyboard, the computer is going to see the character <code>3</code>, and not a raw integer value of <code>3</code>. The Glyph column of that table represents the character value, and the Dec column represents the raw integer value representing that character in the ASCII scheme. You can also see the Binary representation in that table, which is what the Dec integer value breaks down to for how a computer actually handles that value on the lowest level. In your code, the <code>charCode</code> variable is being assigned the dec value of the keystroke (via <code>e.which</code> or <code>e.keyCode</code>, where <code>e</code> looks to be the base JavaScript <a href="https://developer.mozilla.org/en-US/docs/Web/API/Event" rel="nofollow"><code>Event</code> object</a>), which is of type <code>Number</code>. This is why the <code>switch</code> further down in the code is comparing <code>charCode</code> against numerical values. You can switch between characters and their dec values in JavaScript with the <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/fromCharCode" rel="nofollow"><code>fromCharCode()</code></a> and <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/charCodeAt?redirectlocale=en-US&redirectslug=JavaScript/Reference/Global_Objects/String/charCodeAt" rel="nofollow"><code>charCodeAt()</code></a> functions.

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.
