Save as Word doc

edit

There is no such icon available in the Customize menu (Tools > Customize > Toolbars). It might be possible to write a macro to do this, but I don't know for sure.

Depending on how you intend to use it, adding "Save As" or "Export" to the toolbar might get you half way.

Here is a macro that I use to export from Writer/Calc/Impress to Microsoft's X-d formats. I don't remember who is the author of the original code, I just modified it. Warning: it fails on spreadsheet and presentation files (I am not skilled enough to understand the problem). However, it does export from Writer to DOCX.
