Get custom installation

Hi, this is weird but I want to change the installation of a file for a particular user, something like if I press Next with Ctrl+Shift I trigger the copy of a different file.
is it something feasible or it's something crazy to do?

thanks

bye

sounds crazy but if that's really what you want to do...

try using the system plugin and testing
GetKeyState(VK_SHIFT) < 0 to see if Shift key is pressed
