typedef struct tagTOGGLEKEYS {
UINT cbSize;
DWORD dwFlags;
} TOGGLEKEYS, *LPTOGGLEKEYS;
cbSize
Type: DWORD
Specifies the size, in bytes, of this structure.
dwFlags

A set of bit flags that specify properties of the ToggleKeys feature. The following bit flag values are defined:
An application uses a TOGGLEKEYS structure when calling the SystemParametersInfo function with the uiAction 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 SPI_SETTOGGLEKEYS value.
