Mail merge will not require you to perform any coding.  From the Tools menu
in Access, select Office Links and then Mailmerge with Word.

I have a nice working sample that does a merge of the current record to
word.

The sample I have can be found here:
http://www.members.shaw.ca/AlbertKallal/msaccess/msaccess.html

What is nice/interesting about my sample is that is specially designed to
enable ANY form with ONE LINE of code....

Thus, each time you build a new form, you can word merge enable it with
great ease.

Make sure you read the instructions from above, and you should eventually
get to the following page
http://www.members.shaw.ca/AlbertKallal/wordmerge/page2.html

Note that the merge can also use a query, and thus you don't have to merge
just "one" record..

After the merge occurs, you get a plain document WITHOUT any merge fields,
and this allows the end user to save, edit, or even email the document
(since the merge fields are gone after the merge occurs).

Give the above a try.

I also don't use bookmarks, but use the standard merge fields. And, it like
notable that my access code actually creates a csv file, and then I set word
to use that csv file as a data source. I do this for increasing reliability,
and NEVER let word actually connect to the ms-access database (as that can
cause a lot of problems....one of which word tries to launch anohter copy of
access!).
