KeyValues

EntityGroup[0] ([todo internal name (i)]) to EntityGroup[15] <targetname>

Note:The array can be extended beyond 16 entities. Simply add additional Group## keys with SmartEdit turned off.

Also displayed in Hammer's 2D views and Entity Report.

CallScriptFunction <stringRedirectInput/string>
