Switching between applications, windows, and tabs is a fundamental action of modern computers. As people browse the web, we know that an average user will switch tabs more times in a day than they click on a link. Think about that. Much of your time using a modern browser (computer) is spent in the digital equivalent of shuffling papers.
Every major OS provides an “alt-tab” interface: a keyboard shortcut for quickly switching between windows and applications. To use it, you tap alt-tab and you are jumped back to the last focused window. Tap multiple times to cycle through all open applications. It seems simple enough, but there’s a interface gorilla in the room: What order should the applications be shown and cycled through?
