Question

I would like After the Deadline to react onMouseOver instead of onClick when I click on a highlighted error in the text. Here is an atd demo:

I suspect this line in line 177 of editor_plugin.js is responsible

editor.onClick.add(plugin._showMenu, plugin);

When I change this to onMouseOver it complains that there is no such event in TinyMce.

Answer 1

This is correct: onMouseOver is not a tinymce event (tinymce uses its own event handlers).
The solution looks something like

$(editor.getBody()).bind('mouseover', function (evt){
        alert('place code here');   
    }
);
