that's something special we threw in there
What you are seeing are items in the Chart Ribbon's Quick Access Toolbar (QAT for short).
Make the ribbon visible
Right click on the button or other control (or even a section) that you wish to add to the QAT and select "Add to Quick Access Toolbar"
NOTE: the order is the order in which you add the items, so plan ahead. Also keep in mind that all windows of the same type will share the QAT setup. (Intraday Charts, Hist Charts, Level II, etc)
You also can put the QAT BELOW the ribbon, instead of on the caption, or if the ribbon is closed, it would be directly below the caption and would act as a very small toolbar. This can be handy since that gives you more area to put buttons on.
