use a printer driver such as EPrint  to print out outline in Word format.
 
this is only way to get the specially set outline format numbering into Word directly.
 
 
can use the MagicMerge tool and merge to a template in Word that inserts appropriate outline numbering.  If you understand word very will this is pretty darn easy to do.  Will not retain colors, & text formatting from ecco file.
 
 
Can use the slang extension and the slang outline copy (see eccotools.com board)  to copy & paste into word with outline numbering,  but structure is fixed.
 
 
Can also clip & paste to magicview page and add outilne numbering & set A/1/i/I etc. for each level manually.  (this is likey least effective solution).
