Quite frankly, I was kind of hoping someone already knew how to make it happen in X11 and would generously donate that knowledge to the Upp code base. If it is simply impossible, I will have to reconsider if I should anymore use key bindings to Scroll Lock at all.

I guess there is nothing wrong using them as long as you are doing Win32 application.
Anyway, the whole point of all these functions is to make it portable. Calling "(GetKeyState(VK_CAPITAL) & 1)" in Win32 app does look like a big deal to me
