The Word Export feature exports your map in outline form to Word. Only visible topics are exported. This means you can apply a filter or subsequent filters to hide a set of topics you don't want to include in the document.
If you want to include a graphical image of your map in a Word document, you can achieve this by creating an image file from your map and then inserting this into Word.
To save the map in a Word document in outline form:
Do one of the following:
Click File - Save As. In the Save as: list of file types select MS Word Documents (*.doc, *.dot).
Click the
Word export button
on the bottom export toolbar.
Click File - Export - Microsoft Word Export.
To export only selected topics, right-click
on one of the topics and click Send to...
- Microsoft Word.
(Only the selected topics are exported. If a document is already
open, the topics are added at the end of the document.)
The Word Export Settings dialog appears, so you can tailor the export to your liking.
Hint: Take a look at the map in Outline View first for a general idea of what the exported Word file will look like.
In the General
tab, choose the outline numbering scheme, which information to include,
and export options for other map elements. 
In the Word
Template tab, select the Word template you want to use for the document
and how topic levels correspond to different Word styles.
In the Advanced
tab, select the treatment for relationships, hyperlinks, attachments and
map graphics.
Click Export when you have set the options to your liking.
A message appears when the export is done (except when you use the Send to... option.)
Select Open Folder to open the folder that contains the new document
Select Open to open the new document in Word.
Select Close to return to the map in MindManager.
Note: by default, bitmaps are converted to metafiles on export for better compatibility with some RTF readers. Use the Tools - Options - Notes setting Convert bitmaps to metafiles to disable this behavior.
Hint: You can quickly create a simple text outline of your map in Word by this method: select the Central Topic, press Ctrl+C (or Edit -Copy), switch to Word and press Ctrl+V (or Edit - Paste).
