Why don't you just read the source?

https://github.com/SFML/SFML/blob/master/src/SFML/Window/Win32/InputImpl.cpp

I asked for events, not for direct check key!

Then go dig up the event code.
You have the source, just look it up.

We every frame call > wIn.pollEvent(eV)
But where accumulate events to Event object.....
No else functions calls to do check and approve event.

For example - if You click LMouse when your code will be change game world.
Your click accumulate to buffer.
But what it does I cant understand now.
If you know show me where this in winAPI.
Thanks in advance.

And for my research - event object read every event from winApi buffer.

Ok read next sources sfml.
Entry method is > void WindowImplWin32::processEvents

Then winAPI PeekMessage, TranslateMessage, DispatchMessage.
And no see where setted Event.
Only see after this setting MSG message object.

Damn its very tangled logic.
And no one answer me.

Anyways I'm closing research both Shifts triggered event issue.
Too tired )).

Thanks, its real answer )).
But no see where first call to processEvent(), only see to processEvents().

Need to debug on call stack.

Helpfully info!
Need to read msdn to understand more.
Troubles to detect work after DispatchMessage(&message);
