simply add:
local cam = GetCamera('WorldCamera')
cam:SetTargetZoom(150)
function ACUSelectCG()
local curTime = GetSystemTimeSeconds()
local diffTime = curTime - lastACUSelectionTime
if diffTime > 1.0 then
ConExecute('UI_SelectByCategory +nearest COMMAND')
else
ConExecute('UI_SelectByCategory +nearest +goto COMMAND')
local cam = GetCamera('WorldCamera')
cam:SetTargetZoom(150)
end
lastACUSelectionTime = curTime
end
