This would allow the developer the ability to easily add new functionality. For example: If I wanted to make a button that took the selection, and opened a more info window for extra data (just a simple example). Using this method, I could add a class to the selection. Then open a more info window, which would force the selection to be removed (that I could cache). But I have access to all the items that it modified, not just the range that it changed. Since I have access to all of the nodes that changed, I can manipulate them after the selection has been removed and focus has been lost. Then when I am finished, I can use my cached data from the selection to create the selection again. AFAIK, a selection object gives you the data about some of the elements, but not all of the containing elements (especially in the situation I have as an example on the site). There is also the use case of someone selecting part of a node (like in between tags) and executing a command, some commands will auto select the node others won't. The modifiedNodes command would allow us to get that data. Does all that make sense? Dav
