I am just starting to use a Nucleo-L476RG demo board that comes with code that flashes the LED at fixed rates selected by the switch. Where can I find the source code for that application?

You find similar examples in the STM32L4 firmware. It is installed by STM32Cube software or can be downloaded separately. Under Win10 like %USERPROFILE%\STM32Cube\Repository\STM32Cube_FW_L4_V1.14.0\Projects\NUCLEO-L476RG\Examples\GPIO\GPIO_IOToggle.

As above, use your CubeMX/CubeIDE repository, or download the CubeL4 archive and unpack it.

Thanks for the help in pointing that out. The documentation points toward the website for examples, which confuses the issue somewhat. Thanks for clearing it up for me.
