<h3>Working with EditorBase</h3>
<p>`EditorBase` is not a fully functional Editor, it is simply the base utility that will be used under the hood to create an Editor.</p>
<h3>Creating the Editor</h3>
<p>In this step we are going to do the initial render of the Editor, set its content, and focus it when it's ready.</p>
```
YUI().use('editor', function(Y) {
//Create the Base Editor
var editor = new Y.EditorBase({
content: '<p><b>This is <i class="foo">a test</i></b></p><p><b style="color: red; font-family: Comic Sans MS">This is <span class="foo">a test</span></b></p>',
extracss: '.foo { font-weight: normal; color: black; background-color: yellow; }'
});
//Rendering the Editor.
editor.render('#editor');
});
```
<h3>Registering a new execCommand</h3>
<p>ExecCommand overrides are stored on the `execCommand` plugin. This way, you can write a plugin for Editor and have it available
to all Editor instances in your sandbox.</p>
<p>To create a new execCommand, we simply add an object literal to the `Y.Plugin.ExecCommand.COMMANDS` static object like this:</p>
```
foo: function(cmd, val) {
logFn('You clicked on Foo');
var inst = this.getInstance();
inst.one('body').setStyle('backgroundColor', 'yellow');
}
});
```
<p>Now we can use this new command like:</p>
```
editor.execCommand('foo');
```
