linking split screen to index cards?

Hello,
I just started using this program and this is probably a simple solution but I can’t figure it out: Can I set it up so that when using split screen, I can select an index card on the corkboard (top split screen) and that will bring up that notes on the bottom split screen? As of now I have to use the binder and click select the top or bottom split screen to access the infomation when I really just want to click the index card instead.

In the footer bar of the Corkboard, click the button with two opposing arrows. It should turn blue. Now clicking on a card will automatically load the contents of it in an opposing split (can be top, bottom, left, or right–that’s up to you), opening a new split if necessary.
