I downloaded the code from the ckEditor but how can I add the plug in? So far I have added it to the plug in folder but how do I configure it so it's used.
Here's my config set up. I am not sure in particular how to add the button?
config.toolbarGroups = [
{ name: 'document', groups: ['Source', 'mode', 'document', 'doctools', 'maximize'] },
{ name: 'clipboard', groups: ['clipboard', 'undo'] },
{ name: 'editing', groups: ['find', 'selection', 'spellchecker'] },
{ name: 'forms' },
{ name: 'basicstyles', groups: ['basicstyles', 'cleanup'] },
{ name: 'paragraph', groups: ['list', 'indent', 'blocks', 'align', 'bidi', 'justify'] },
{ name: 'insert' },
{ name: 'styles' },
{ name: 'colors' },
{ name: 'tools' },
{ name: 'others' }
];
config.extraPlugins = 'insertpre,format,justify,maximize,sourcearea';
