;Window's SystemParametersInfo function, retrieves or sets the value of one of the 
;system-wide parameters.  AHK DllCall fxn with SystemParameterInfo parameter is used to access
;this Windows API.
;https://msdn.microsoft.com/en-us/library/windows/desktop/ms724947(v=vs.85).aspx
;BOOL WINAPI SystemParametersInfo(
;  _In_    UINT  uiAction,
;  _In_    UINT  uiParam,
;  _Inout_ PVOID pvParam,
;  _In_    UINT  fWinIni
;);

;uiParam [in]
;Type: UINT
;
;A parameter whose usage and format depends on the system parameter being queried or set. 
;For more information about system-wide parameters, see the uiAction parameter. 
;If not otherwise indicated, you must specify zero for this parameter.

;pvParam [in, out]
;Type: PVOID
;
;A parameter whose usage and format depends on the system parameter being queried or set. 
;For more information about system-wide parameters, see the uiAction parameter. 
;If not otherwise indicated, you must specify NULL for this parameter. 
;For information on the PVOID datatype, see Windows Data Types.

;fWinIni [in]
;Type: UINT
;
;If a system parameter is being set, specifies whether the user profile is to be updated, 
;and if so, whether the WM_SETTINGCHANGE message is to be broadcast to all top-level 
;windows to notify them of the change.

;This parameter can be zero if you do not want to update the user profile 
;or broadcast the WM_SETTINGCHANGE message or it can be set to the following [...]

;Accessibility parameter    
;S0x101D PI_SETMOUSESONAR
;Turns the Sonar accessibility feature on or off. This feature briefly 
;shows several concentric circles around the mouse pointer when the user 
;presses and releases the CTRL key. 
;The pvParam parameter specifies TRUE for on and FALSE for off. 

;Press the control button each time mouse button is pressed, showing location of mouse pointer.
