This structure contains information about the toggle keys accessibility option. When the toggle keys option is on, the device emits a high-pitched sound whenever the user turns on the CAPS LOCK, NUM LOCK, or SCROLL LOCK key and emits a low-pitched sound whenever the user turns off one of those keys.

  UINT cbSize;
  DWORD dwFlags;
} TOGGLEKEYS, *LPTOGGLEKEYS;

cbSize

Unsigned integer that specifies the size, in bytes, of this structure.

dwFlags

When using SPI_GETTOGGLEKEYS, you must specify the cbSize member of the TOGGLEKEYS structure; the SystemParametersInfo function fills in the remaining members. Specify all structure members when using the SPI_SETTOGGLEKEYS value.
