Sorry if this too dumb, but I've searched for hours, to clic,  double clic, or on any kind of other clic, on any side of the pop up messages who advise me about short-cuts, without finding how to move or close them !! :(

These pop-up message are just on front of the map I try to create, hiding what I try to do, and neither can I move nor close them...

Drive me crazy : help please !!!
