How to paste in the icon from the icon palette

I love the idea of being able to make icons. That part I understand. But, I can’t see how I can paste the icon that I made anywhere.
I have no background to understand that directions in the manual. Or should I just wait for version 7.0 of KM?

In Edit mode, select the desired macro, then click on the image. Make any change in the Icon Chooser, or alternatively click on the icon in the Icon Chooser, and the icon for the macro will be set.

Tip: to “load” the icon from the macro into the choose to make further changes, select the icon in the macro first, and then open (or close and then open) the Icon Chooser.

Very nice.
