<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>

```

Y.mix(Y.Plugin.ExecCommand.COMMANDS, {

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');

```
