Make Caps Lock to Behave Differently

[Alex Petrovsky]

Hello,

I like the idea of using Caps Lock as Fn, where when Fn is pressed I use IJKL as arrows. It works great now.

However, sometimes I do actually need Caps Lock, so I was thinking if it's possible to make it act like a regular Caps Lock if I quickly press it VS. make it act like it's Fn when I'm holding it and still not activating Caps Lock after releasing.

I was able to to achieve the first part, but it wasn't acting as Fn when I was pressing it, it wasn't doing anything. 

Does anyone know if it's even possible and what am I missing? The code is below.

Thanks,
