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;

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.
