Alright, upon further investigation it definitely seems like this is a Mac issue, and I guess I remembered wrong because none of my custom boards have a working Num Lock on Mac!!
Is there any way to toggle a function layer on? I see that the 1.9a firmware has a FN TOGGLE switch option. Is there any way to do that with the 1.x? I could basically make my own Num Lock mode like this. I don't want to have to keep the Function key pressed...
This I can help you with!
For clarity sake,
Lightsaver has Layer 1, 2, 3, 4 and Layer FN 1, 2, 3.Edit:Ly 1-4 will set your keyboard to Layer 1-4 respectively.
If you set your Num Lock to "Ly 2" and then on Layer 2 set Num Lock to "Ly 1" I believe you'll get the effect you're looking for.
Layer TG is layer toggle.(not sure how it works) Layer CH is layer change.(Pretty sure it moves to the next layer. Ly+1)
MFN is the key you're looking for.(old info kept for others to see)
Info for others.
If you hold MFN you access the Layer FN 1.
MFN, I have concluded, stands for multi-function.
If you press the MFN key twice, and hold it on the second press, you access Layer FN 2;
on the third press, you get Layer FN 3.
