Some other keys that work while using Cmd+Tab:

- Press "q" to quit the selected application

- Press "h" to toggle hiding the selected application

- Press "1" to show all open windows for the selected application

Does anyone know if there is a built-in way to only switch to the frontmost application window (by default Cmd+Tab puts all app windows in the foreground)? Sometimes I need to switch between two windows of different applications which I both want to keep visible on the screen, but switching to the destination app with Cmd+Tab ends up covering the entire screen because that application has other windows.
