I was certain I had written a blog post about this. It appears that I haven’t.
In any case, this is in great detail being presented in the MSDN Blogs.
The solution consists of a few keyboard shortcuts so what you need to do is simply:
1. Open the data source task pane
2. Type the “F6” key
3. Click tab (the actual tab key) until a field in the data source is highlighted in orange
4. Use the Up/Down arrow keys to select the field you want to move
5. Hold down the CTRL key and use the Up/Down arrow keys to move the field
….genius! Thanks a lot!
