用AutoHotkey调整Windows音量

我用了【右Alt】+方向键来调整音量：Alt+上下键，音量调整幅度为5，如果再增加个右Ctrl，音量调整幅度为1。

Alt+左键为静音，Alt+右键为最大音量。

>!Up::    ;音量+
<!Down::  ;音量-
^!Up::   ;音量+
^!Down:: ;音量-
Sound_Add := InStr(A_ThisHotkey, "^") ?  :
If InStr(A_ThisHotkey, "Up")
    hyf_SoundSetWaveVolume("+", Sound_Add)
Else
    hyf_SoundSetWaveVolume("-", Sound_Add)
Return

>!Right:: ;音量最大 {{{
