Writing code. at least in open office you can create a new HTML document, don't have Word with me right now but in the old days I believe it was possible.
Well, you sure can save a Word document as HTML, but it spits out some of the grossest, most xml-metadata-crammed, non-human-readable HTML and CSS you have ever seen. God help you if you actually want to use Word as a WYSIWYG HTML editor. And have fun trying to add JS to it...
