<a href="https://wordpress.org/extend/plugins/ckeditor-for-wordpress/" rel="ugc">CKEditor For WordPress</a> plugin replaces the default WordPress editor with CKEditor, while <a href="https://wordpress.org/extend/plugins/auto-syntaxhighlighter/" rel="ugc">Auto SyntaxHighlighter</a> plugin intergrates alexgorbatchev SyntaxHighlighter JavaScript package into WordPress but doesn’t provide a code button for CKEditor. This is why I created the plugin.
