copied!<p>I believe these are predefined Firebug console functions - at least that seems to be the case for Firebug. If you try calling <code>window.copy</code> for instance, you'll get a warning about function not defined, so it's definitely not a browser function, and cannot be used in normal JavaScript files. The following functions also seems to work in the JavaScript console, after playing around with it a bit: </p> <ul> <li><code>clear()</code> </li> <li><code>profile()</code></li> </ul> <hr> <p>Running these in the Chrome console reveals the source behind these functions in the Webkit console: </p> <pre><code>> profile function () { return console.profile.apply(console, arguments) } > clear function () { InjectedScriptHost.clearConsoleMessages(); } > copy function (object) { if (injectedScript._type(object) === "node") object = object.outerHTML; InjectedScriptHost.copyText(object); } </code></pre> <p>While the <a href="http://code.google.com/p/fbug/source/browse/branches/firebug1.7/content/firebug/commandLine.js?r=8810#1169" rel="noreferrer">Firebug source</a> also defines a list of functions: </p> <pre><code>this.clear = function() // no web page interaction { Firebug.Console.clear(context); }; this.inspect = function(obj, panelName) // no web page interaction { Firebug.chrome.select(obj, panelName); }; this.keys = function(o) { return FBL.keys(o); // the object is from the page, unwrapped }; this.values = function(o) { return FBL.values(o); // the object is from the page, unwrapped }; // etc... </code></pre>

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