      SV_KBDALTERED
        (*) Hardware ID of the newly attached keyboard.

        Note: The OS/2 National Language Support is only loaded once per system IPL. The OS/2 NLS translation is based partially on the type of keyboard device attached to the system. There are two main keyboard device types: PC AT styled and Enhanced styled. Hot Plugging between these two types of devices may result in typing anomalies due to a mismatch in the NLS device tables loaded and that of the attached device. It is strongly recommended that keyboard hot plugging be limited to the device type that the system was IPL'd with. In addition, OS/2 support will default to the 101/102 key Enhanced keyboard if no keyboard or a NetServer Mode password was in use during system IPL. (See Category 4, IOCtls 77h and 7Ah for more information on keyboard devices and types.)

      SV_LOCKSTARTINPUT

        (*) The delay in milliseconds before hiding a pull down referred to from a submenu item, when the button is already down as the pointer moves off the submenu item.
      SV_MONOICONS
        (*) When TRUE preference is given to black and white icons when selecting which icon resource definition to use on the screen. Black and white icons may have more clarity than color icons on LCD and Plasma display screens.
      SV_MOUSEPRESENT
        When TRUE a mouse pointing device is attached to the system.
      SV_NOTEDURATION
        (*) Duration for note alarms generated by WinAlarm.
      SV_NOTEFREQ
        (*) Frequency for note alarms generated by WinAlarm.

      SV_OPENKB
        (*) Keyboard open (low word=virtual key code (VK_*), high word=keyboard control code (KC_*)).
      SV_POINTERLEVEL
        Pointer hide level. If the pointer level is zero, the pointer is visible. If it is greater than zero, the pointer is not visible. The WinShowPointer call is invoked to increment and decrement the SV_POINTERLEVEL, but its value cannot become negative.
      SV_PRINTSCREEN
        (*) TRUE when the Print Screen function is enabled; FALSE when the Print Screen function is disabled.
      SV_SCROLLRATE
        (*) The delay (in milliseconds) between scroll operations, when using a scroll bar.

      SV_TASKLISTMOUSEACCESS
        (*) Determines whether the task list is displayed when mouse buttons 1 and 2 are pressed simultaneously, or when mouse button 2 is pressed by itself, or for no mouse gesture.
      SV_TEXTEDIT
        (*) Mouse begin direct name edit (low word=mouse message id (WM_*), high word=keyboard control code (KC_*)).
      SV_TEXTEDITKB
        (*) Keyboard begin direct name edit (low word=virtual key code (VK_*), high word=keyboard control code (KC_*)).
      SV_TRACKRECTLEVEL
        The hide level of the tracking rectangle (zero if visible, greater than zero if not).
      SV_SWAPBUTTON
        (*) TRUE if pointing device buttons are swapped. Normally, the pointing device buttons are set for right-handed use. Setting this value changes them for left-handed use.

        If TRUE, WM_LBUTTON* messages are returned when the user presses the right button, and WM_RBUTTON* messages are returned when the left button is pressed. Modifying this value affects the entire system. Applications should not normally read or set this value; users update this value by means of the user interface shell to suit their requirements.

      SV_WARNINGDURATION
        (*) Duration for warning alarms generated by WinAlarm.
      SV_WARNINGFREQ
        (*) Frequency for warning alarms generated by WinAlarm.
