TOGGLEKEYS info  Overview  Group

The TOGGLEKEYS structure contains information about the ToggleKeys accessibility feature. When the ToggleKeys feature is on, the computer emits a high-pitched tone whenever the user turns on the CAPS LOCK, NUM LOCK, or SCROLL LOCK key, and a low-pitched tone whenever the user turns off one of those keys.

typedef struct tagTOGGLEKEYS {     // tk 

    DWORD cbSize; 

    DWORD dwFlags; 




Specifies the size, in bytes, of this structure.
A set of bit flags that specify properties of the ToggleKeys feature. The following bit flag values are defined:




If this flag is set, the ToggleKeys feature is available.


Windows 95 only: A confirmation dialog box appears when the Togglekeys feature is activated by using the hot key.


If this flag is set, the user can turn the ToggleKeys feature on and off by holding down the NUM LOCK key for eight seconds.


If this flag is set, the system plays a siren sound when the user turns the ToggleKeys feature on or off by using the hot key.


If this flag is set, the ToggleKeys feature is on.


An application uses a TOGGLEKEYS structure when calling the SystemParametersInfo function with the wAction parameter set to SPI_GETTOGGLEKEYS or SPI_SETTOGGLEKEYS. When using SPI_GETTOGGLEKEYS, an application must specify the cbSize member of the TOGGLEKEYS structure; the SystemParametersInfo function fills the remaining members. An application must specify all structure members when using the SETTOGGLEKEYS value.
