Hotkey for chart: Switch to next symbol of watchlist

When viewing a chart, I want to go quickly switch to the next symbol that is on my watchlist, to quickly browse all my symbols on the chart in full view. At the moment, it takes a few mouseclicks. Or I have to open de Trade-tab on the left side, but that eats a lot of space on my screen.

Refer to image. When viewing this, I want to be able to click (for example) Alt+N to switch to see the next symbol on this chart.
