Create a container with a text box and an editbox. The editbox is hidden and disabled. Then in the interactivechange of the text box I'd wait for a '+' (or whatever), when it is found then get the contents of the text box, disable the text box and hide it, enable and display the edit box and put the contents of the text box into it, put the cursor at the end of the text, give focus to the edit box. In the valid of the the edit box just get the contents, hide it, process the contents, put the result in the text box and show it. Never tried doing it but it might just work
