How to re-arrange style items in Quick Style list in Microsoft Word?
If the below method doesn't work, then maybe you have a different version of Word than me. I'm using Office 2010. In that case, view this link.
STEP 1
Click on the down-right arrow, below the "Change Styles" button on the right.
STEP 2
A Styles window will appear, as shown in the image below. Click on the "Manage Styles" button : 3rd button beside the "options..." , the button on the bottom right.
STEP 3
Click on Recommend on the manage styles screen and from here you can move your style up or down the list to re-order it.
