How do I change the ticker symbol for all charts of layout simultaneously?

You are able to adjust all of your charts by using a multi-chart layout. You will also be able to see the same or different ticker symbols on them. Here is how it's done. Open the chart layout menu and enable/disable symbol syncing.

Another way to change the symbol on all chart layouts simultaneously (even when syncing is disabled) is to double-click a symbol in the watchlist.
