Answer 2

Hwnd = Plugin.Window.GetKeyFocusWnd()
Delay 2000

t1=now:t2=now:sj1=0.5:sj2=60
Rem abcc
Delay 20
If DateDiff("s",t1,now)>=sj1

Delay 10

Call Plugin.Bkgnd.KeyPress(Hwnd, 83)
Delay 10
t1=now
End If
If DateDiff("s",t2,now)>=sj2
Delay 10
Call Plugin.Bkgnd.KeyPress(Hwnd, 70)
t2=now
End If
Goto abcc
