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.

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.
