Hi Anton, To insert text, use insertText(location, text). "location" can either be an int or a Point. Try to use integer locations as much as possible, "Point"s can be tricky and bug prone.
ALL document mutations must be done through the document interface, because that takes care of handling sending operations out to the server so other clients see them - you cannot modify the document by directly manipulating the nodes. See methods on MutableDocument. Try this: document.insertText(range.getFocus(), "Some text") (getFocus() is fine, why do you want Math.min? If you really want to, you could also use a Range and call getFirst() instead of using a FocusedRange, e.g. SelectionHelper.getOrderedSelectionRange()).
