If I understand secondary function correctly, that’s essentially what the FN key does on keyboards it switches it from F1 through 12 to 13 through 23, but they generally use the buttons to control system settings such as your brightness or audio. The FN lock just switched the polarity so it defaults to 13 through 23 instead of 1 through 12
