I don’t work with MS Word all the time, so I end up having to re-discover this trick each time.
Firstly, this is nothing new. In fact, I’m basically cribbing the steps from here:
The reason I’m putting it into my blog is so I know it’s here and can search a smaller field than the whole of the internet. If you’ve any kudos, please send it to the original URL.
This works with MS Word 2007, 2010, and 2013. The controls are different with earlier versions of MS Word, but I’m sure there is a way to map the steps to those legacy versions.
In conclusion, this is really harder than it needs to be. Some of the web pages detailing this suggests exporting it as a template, but I’d much rather Word came with this a simple control.
