FWIW it works for me but you may see different results, the function keys are overloaded and the OS or some other app you're running may grab one of these shortcuts. That's why this test avoids Cmd-F5, on Ventura that toggles Voice Over.

@beldenfox 
Sounds good, I looked at a the test.
The test will need some changes to adapt to other platforms, otherwise looks good.
