Watch List changes chart with cursor

I'd like the ability to change the contract being viewed in the chart by simply using up/down cursor on the keyboard.

You can see CLU7 is highlighted.  I'm requesting the ability to say click the up arrow on my keyboard, which would move that blue highlight up and therefore change the charts from CLU7 to NQU7 in this example.

This would allow me to keep my eyes on the chart, instead of having to look at another screen to make sure my mouse in over the current place to change the quote/chart.
