What shortcut can be used to bring focus back to the workflow after working on other applications?

The correct shortcut to bring focus back to the Alteryx workflow after working in other applications is Alt + Tab. This keyboard shortcut is commonly used in many operating systems, including Windows, to switch between open applications. By holding down the Alt key and tapping the Tab key, you can cycle through the list of currently running applications. Releasing the keys while highlighting the desired application will bring it to the forefront, allowing you to continue your work in Alteryx seamlessly.

Other shortcuts mentioned may have different functions or applications. For example, Ctrl + Tab typically allows users to switch between tabs in applications that support tabbed interfaces, such as web browsers or certain text editors. Ctrl + R often performs a refresh action in various environments, and the Esc key is usually associated with canceling actions or closing dialog boxes, rather than switching focus between applications. Therefore, Alt + Tab is the most appropriate choice for returning focus to the Alteryx workflow.
