Objects are on the chart. "Moving" makes no sense. What are you "moving?"
If you mean selecting the next one, code your OnEvent for a tab, and when triggered go through the list, find the currently selected one, deselect it and select the next one.
We're not going to code it for you (although it could happen if
you are lucky or the problem is interesting.) We are willing to help you
when you post your attempt (using SRC) and the nature
of your problem.
