Switching between multiple open windows in the same application has always been a pain point for me. Go to Window in the application Menu Bar and then select the window I want from the list of open windows. Or right click on the application in the Dock and select the window from list of open windows.
I just learned that there’s an easier way. Use the keyboard shortcut ⌘ + Tilde to quickly switch between open windows in the same application. So, for example, there are times when I have several Safari windows open at the same time. I can quickly sort through them with this keyboard shortcut.
Next time you have several windows open in the same application give it a try.
