#Requires AutoHotkey v2.0
#SingleInstance Force

; as a flag for Switching Apps process status
global isAltTabbing := false

        isAltTabbing := true
        Send "{Alt Down}{Tab}"
    } else {
        Send "{Tab}"
    }
}

~LCtrl Up::
{
    global isAltTabbing
    if (isAltTabbing) {
        Send "{Alt Up}"
        isAltTabbing := false
    }
}
