Detecting shift with wait for key

[Spyda]

I am trying to remap 4 keys to behave as another key(Ex. Push <w> screen types "e"). What is ouputted can be any key, and when using RegisterHotkey if a programmed key's value is another programmed key, the first programmed key triggers the third (Ex push <w>, triggers <e> push, does not output "e").
