    <p>I'm working yet on a small script to capture keyevents and easily bind functions on them. But I'm stuck for now!</p> <p>The problem is, that if I initalize more than one "eventhandler" it overides arguments from the first initialization.</p> <p>Thousands of words do not say more than some lines of code. So, here's what I've done so far:</p> <pre><code>var keyCodes={a:65,b:66,c:67,d:68,e:69,f:70,g:71,h:72,i:73,j:74,k:75,l:76,m:77,n:78,o:79,p:80,q:81,r:82,s:83,t:84,u:85,v:86,w:87,x:88,y:89,z:90,"0":48,"1":49,"2":50,"3":51,"4":52,"5":53,"6":54,"7":55,"8":56,"9":57,f1:112,f2:113,f3:114,f4:115,f5:116,f6:117,f7:118,f8:119,f9:120,f10:121,f11:122,f12:123,shift:16,ctrl:17,control:17,alt:18,option:18,opt:18,cmd:224,command:224,fn:255,"function":255,backspace:8,"delete":8,enter:13,"return":13,left:37,up:38,right:39,down:40}; var keyCall = function(k, fn, c, e, k2, nk) { this.onkeydown = function() { nk = k.split(" "); c = e ? e.which : event.keyCode; if (nk.length &gt; 1) { if (keyCodes[nk[0]] === c) { k2 = true; } if (keyCodes[nk[1]] === c &amp;&amp; k2 === true) { fn(); k2 = false; } } else if (keyCodes[nk[0]] === c) { fn(); } }; }; keyCall('ctrl a', function() { // overridden by `keyCall('shift a'` alert('callback1'); }); keyCall('shift a', function() { alert('callback2'); }); </code></pre> <p>I've optimized it for a highly minimum of bytes, if you think an annotated version is usefull, so just say it! For everyone who needs, here's a <a href="http://jsfiddle.net/ARTsinn/HLUYt/" rel="nofollow">fiddle</a></p> <p><strong>Update</strong></p> <p>pascalfree has fixed it! But anoter problem is now coming up... </p> <p>The "placeholder"-variable <code>k2</code> checks if the first key was/is pressed. But for now if you press and release <code>ctrl</code> and hit thereafter the <code>a</code>-key the function will fired. Any ideas?</p>

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.
