Answer 2

I am assuming that you are using Windows[1]. This answer will not work on other platforms.Your best bet would be to use the SendInput() API function to simulate WM_KEYDOWN and WM_KEYUP messages on the Scroll Lock Key.

See http://msdn.microsoft.com/en-us/library/ms646310%28v=VS.85%29.aspx.

[1] I base my guess on the following: *nix users (including Mac users) normally state their platform. Those who are unaware of other platforms are usually Windows users. :-)
