Greetings all, I propose to implement selectionchange event, an event dispatched whenever selection changes. This event allows developers to be notified of selection change, and can be used to update status for RTE (e.g. toggling the appearance of bold button based on the context around caret). This event has already been implemented by Internet Explorer for document node<http://msdn.microsoft.com/en-us/library/ms536968(VS.85).aspx> .
For example, if you do: document.addEventListener('selectionchange', function () {alert("selection changed!"), false); alert is shown whenever selection changes inside the current document. I'd like to make this event attachable to other elements as well so that developers can be notified of only relevant selection changes (target element is always document in MSIE's implementation). For example, we can easily extend this event to be fired from root editable elements because selection does not cross editing boundary. Alternatively, we can extend the existing select event to fire for root editable elements as supposed to fire only for input / textarea elements. For this alternative, see the note in the section 5.2.1. of the DOM Level 3 Events specification where it says: *Note:* The select<http://dev.w3.org/2006/webapi/DOM-Level-3-Events/html/DOM3-Events.html#event-type-select> event may not be available for all elements in all languages. For example, in [ HTML5<http://dev.w3.org/2006/webapi/DOM-Level-3-Events/html/DOM3-Events.html#references-HTML5> ], select<http://dev.w3.org/2006/webapi/DOM-Level-3-Events/html/DOM3-Events.html#event-type-select> events may only be dispatched on only form input and textarea elements. Implementations may dispatch select<http://dev.w3.org/2006/webapi/DOM-Level-3-Events/html/DOM3-Events.html#event-type-select> events in any context deemed appropriate, including text selections outside of form controls, or image or markup selections such as in SVG.
