STICKYKEYS info  Overview  Group

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; 




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




If this flag is set, the system plays a sound when the user latches, locks, or releases modifier keys using the StickyKeys feature.


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


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


If this flag is set, the user can turn the StickyKeys feature on and off by pressing the SHIFT key five times.


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.


Windows 95 only: A visual indicator should be displayed when the StickyKeys feature is on.


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


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.


If this flag is set, releasing a modifier key that has been pressed in combination with any other key turns off the StickyKeys feature.


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.
