Add Hotkey setting to bring the sidewise window into focus when used without having to first being Chrome into focus

It would be handy to be able to bring the sidewise window into focus at anytime without the need to first click on chrome. For example I may have my several chrome windows hidden / minimized and will be working on other apps. I want to pull up a specific tab / window in chrome without having to first pull up my chrome window and then click the sidewise button to bring up the window.
