nicEdit : Add key(press|up|down) events to editor

I'm using nicEdit to have a RTF textarea and I need to add a `onkeypress`, `onkeyup` or `onkeydown` event. I create my instance like this: ``` var emailRtf = new nicEditor({ iconsPath : 'nicEdit/nicEditorIcons.gif', buttonList : ['bold','italic','underline','fontSize','forecolor','ol','ul','link','unlink','removeformat'], maxHeight: 600}).panelInstance('REPLY_MESSAGE'); ``` I tried the following (with `keypress`, `keydown` and `keyup`): ``` emailRtf.addEvent("keypress", function() { alert('test') }); // Not working emailRtf.addEvent("keypress", function(evt) { alert('test') }); // Not working ``` However, the following works: ``` emailRtf.addEvent("blur", function() { alert('test') }); // Alert shows when I leave focus on the textArea ``` How can I add `key(press|up|down)` to a nicEdit editor? NOTE: I have multiple instance of RTF textarea in my page and I need to add the `key(press|down|up)` event to only one. I found this question, which add the event on all instances. Also, I would like to leave nicEdit.js intact.
