1. : The ? hotkey on the strategic map doesn't list all the hotkeys that are available.
2. : The +/- hotkeys don't work with all keyboard layouts. Under Linux, they do work with a Polish keyboard layout (keycode 20 for "-" and keycode 21 for "+"), but not with a German one (keycode 61 for "-" and keycode 35 for "+"), under Windows they work for some people / keyboard layouts and don't work for others, too.
