Detecting shift with wait for key

[Spyda]

Code:

Copy      Help

[code]rep
,int input=wait(0 KF)
,out GetMod
,out GetAsyncKeyState(VK_LSHIFT)
,out GetKeyState(VK_LSHIFT)
,out RealGetKeyState(VK_LSHIFT)
,if (input = 119) ;; end on f8
,,break
,key (input)

[/code]

How can I detect if shift is down when the key is imputted.
