Text can be cut-and-paste from Microsoft Word with relative ease. But any references or other links contained in the text will be removed as you paste. So you will need to re-enter these.
Export to Microsoft Word is now available. However, this is for submitting writing projects to others (e.g., supervisors and teachers), and not for editing (we export text only). All your editing changes should be done in ComWriter first.
Rule: if it looks good in the exported PDF, then it will look good in Word.
