The default editor in WordPress is lacking, to say the least. If you’re looking to replace the default editor with a more powerful and accessible editor, you should give the CKEditor a try. There’s a long list of reasons why this editor is better. If you don’t like it, simply remove the CKEditor plugin!
To install it, go to Plugins in your WordPress Dashboard, choose “Add new” at the top and do a search for “CKEditor for Wordpess”, choose the one from CKSource and click “Install Now”. (click OK to confirm)
Once it’s successfully installed, click the “Activate Plugin” link. That’s it! Now when you go to “Posts -> Add New” you should notice the new, more powerful editor. Take your time and go through all of these new options you’ve not had before!
