What I do: use View
> Window
> New Window
to open the current workbook in a different application window. Use each window to display one of the sheets you're working with. You can now switch between them using the regular Alt+Tab (on Windows).
This method has another benefit: a workbook can be open in more than two windows, each displaying a different worksheet.
The (possible) disadvantage of this method is that you may need to hit Alt+Tab more than once if another application window has become active since you last looked at Excel.
However, you can also:
- Use the Task View to display all open windows and easily select one Win+Tab;
- If you work with a lot of different applications/documents, put your Excel windows in their own virtual desktop. While you're in that desktop, Alt+Tab will work nicely. You can switch to the 'previous' desktop using Win+Ctrl+Left, then do that again to return to the desktop containing the Excel windows. If I am working on projects, I typically put 'general apps' (browser, email, OneNote) in one virtual desktop, and have a different desktop for each project.
- If you have multiple Excel windows open, and they are grouped together in the Taskbar, you can cycle through them (in the order they were last active) by Ctrl+
Click
ing the grouped taskbar button.
Obviously, each method has different pros and cons, depending on how many applications and documents you have open, and how you want to interact with them.
