Not too intuitive but here is how that works. Right click on the tool bar space either on the left or top area. You will get a drop down tool window listing all visible and non visible tool bars. At the bottom of that window you will see, "ToolBars".
Click Tool bars. This opens a Toolbar dialog box.
NOW, ONLY WHEN THIS TOOLBAR DIALOG BOX IS OPEN...... YOU CAN
Click and drag any icon to any tool bar. With in the ToolBar dialog box you can create a custom and empty tool bar. Drag the icons you want to that tool bar and place the bar where you want.
When you close the ToolBar dialog box you can no longer drag icons.
