|Values:||unsigned integers (represent key codes)|
Specifies the keyboard shortcut used to select all instances of the currently selected object(s). (Meaning, if you hit this key while you have a GI and a GGI selected, all GIs and GGIs will be selected.) Hitting the key once selects only units visible on the screen, hitting it again selects all units on the map. If there are no units to select on the screen, then all units on the map will be selected with the first click.
