TOGGLEKEYS
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;
} TOGGLEKEYS;
Members
cbSize
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:
Value
| Meaning
| TKF_AVAILABLE
| If this flag is set, the ToggleKeys feature is available.
| TKD_CONFIRMHOTKEY
| Windows 95 only: A confirmation dialog box appears when the Togglekeys feature is activated by
using the hot key.
| TKF_HOTKEYACTIVE
| 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.
| TKF_HOTKEYSOUND
| 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.
| TKF_TOGGLEKEYSON
| If this flag is set, the ToggleKeys feature is on.

Remarks
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.
