Space bare don't deselect all / all select ? (or it's an personal shortcut?
and H = hide invert selection (or it's an personal shortcut?

Ps I am thinking of something
Maybe it will be fine to have with the F1 for the Help, a list of Shortkey by Default who arrived with the first Install of the prog?
