How do I only send keydown to a minimized window?

[Seroko]

I've been using DllCall user32.dll ~ to send keypresses (I found an example in an old script and modified it to my needs) and this works fine, but it had no way of just sending keydown, I tried modifying it but nothing worked. Anyone care to help me out here?

tl;dr Need to send keydown / keyup separate to a minimized window using window handle.

HotKeySet("^d", "_Down")
HotKeySet("^u", "_Up")

$hWindow = WinGetHandle("MyTest")


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func _Down()
    WinSetState($hWindow, "", @SW_MINIMIZE)
EndFunc

Func _Up()
    WinSetState($hWindow, "", @SW_RESTORE)
EndFunc

Take a look at the ControlSend() function. An empty controlID should send the keystroke to the window.
