STICKYKEYS
The STICKYKEYS structure contains information about the StickyKeys accessibility feature.
When the StickyKeys feature is on, the user can press a modifier key (SHIFT, CTRL, or ALT) and then another key in sequence rather than at the same time, to enter
shifted (modified) characters and other key combinations.
typedef struct tagSTICKYKEYS { // sk
DWORD cbSize;
DWORD dwFlags;
} STICKYKEYS, *LPSTICKYKEYS;
Members
cbSize
Specifies the size, in bytes, of this structure.
dwFlags
A set of bit-flags that specify properties of the StickyKeys feature. The
following bit-flag values are defined:
Value
| Meaning
| SKF_AUDIBLEFEEDBACK
| If this flag is set, the system plays a sound when the user latches, locks, or
releases modifier keys using the StickyKeys feature.
| SKF_AVAILABLE
| If this flag is set, the StickyKeys feature is available.
| SKF_CONFIRMHOTKEY
| Windows 95 only: A confirmation dialog appears when the StickyKeys feature is activated by
using the hot key.
| SKF_HOTKEYACTIVE
| If this flag is set, the user can turn the StickyKeys feature on and off by
pressing the SHIFT key five times.
| SKF_HOTKEYSOUND
| If this flag is set, the system plays a siren sound when the user turns the
StickyKeys feature on or off by using the hot key.
| SKF_INDICATOR
| Windows 95 only: A visual indicator should be displayed when the StickyKeys feature is on.
| SKF_STICKYKEYSON
| If this flag is set, the StickyKeys feature is on.
| SKF_TRISTATE
| If this flag is set, pressing a modifier key twice in a row locks down the key
until the user presses it a third time.
| SKF_TWOKEYSOFF
| If this flag is set, releasing a modifier key that has been pressed in
combination with any other key turns off the StickyKeys feature.

Remarks
An application uses a STICKYKEYS structure when calling the SystemParametersInfo function with the wAction parameter set to SPI_GETSTICKYKEYS or SPI_SETSTICKYKEYS. When using
SPI_GETSTICKYKEYS, an application must specify the cbSize member of the STICKYKEYS structure; the SystemParametersInfo function fills the remaining members. You must specify all structure members
when using the SPI_SETSTICKYKEYS value.
