How to remove the SCAYT plugin in CKEditor 4?

The WProofreader work in the CKEditor 4 requires turning off the SCAYT plugin. A free version of SpellCheckAsYouType (SCAYT) is provided as a plugin, integrated by default into the CKEditor WYSIWYG editor. To remove the SCAYT plugin from CKEditor 4, add the following line to your CKEditor config.js file:

config.removePlugins = 'scayt';

Set the config.scayt_autoStartup configuration setting as false  to prevent SCAYT from being turned on automatically on loading the editor. In this case, the SCAYT plugin for CKEditor 4 is available but turned off.

config.scayt_autoStartup = false;
