'minimize' => 'clickme', // Language string to use for minimized view. NULL will mean editor is not minimized.

'allButtons' => FALSE, // Only used for the customisation ACP page. Do not use.
'tags' => array(), // An array of extra insertable tags in key => value pair with key being what is inserted and value serving as a description
'autoGrow' => FALSE, // Used to specify if editor should grow in size as content is added. Defaults to TRUE.
'controller' => NULL, // Used to specify the editor controller. Defaults to NULL, which will use app=core&module=system&controller=editor
'defaultIfNoAutoSave'=> FALSE, // If TRUE, the default value will not override any autosaved content
'minimizeWithContent'=> FALSE, // If TRUE, the editor will be minimized even if there is default content
'maxLength' => FALSE, // The maximum length. Note that the content is HTML, so this isn't the maximum number of visible characters, so should only be used for database limits. The database's max allowed packet will override if smaller
'editorId' => NULL, // Passed to editorAttachments. Only necessary if the name may be changed
