Keyboard shortcut to jump between the search box and the search results

Every week I download and update transactions. For the update job, I continually need to jump between the search box and the search results down below (the transactions). When I am in the transactions, I can use Command-F to jump to the search box, but when I'm in the search box, there is no keyboard shortcut (I have been able to find) to jump me back to the search results (i.e. transactions). Could that please be added? It is very frustrating to constantly have to hunt for the mouse when using the keyboard to work through the found transactions.
