Thanks to Bob Hanlon for suggesting: Column[{ Row[{ "a ", Slider[Dynamic[a], {1, 5, 1}], , a = 4; Dynamic[a]}], Row[{ "b ", Slider[Dynamic[b], {1, 5, 1}], , b = 2; Dynamic[b]}], Dynamic[Plot[a + b*x, {x, 0, 1}, PlotRange -> {0, 10}, ImageSize -> 360]]}, Center] It centers the control fine, but does not use Manipulate. If I rewrite the exapmle with Manipuate as Thank you, but I was using Manipulate? here si the equivalent: Manipulate[ Plot[a+b*x,{x,0,1},PlotRange->{0,10},ImageSize->360], {{a,4},1,5,1,Appearance->"Labeled"}, {{b,2},1,5,1,Appearance->"Labeled"}, AppearanceElements->None, Alignment -> Center] The contro lis flush left again, the option Alignment acts only in the white Display area and not on the controls. The option ControlPlacement appears somewhat limited and has no Center setting. Options[Manipulate] shows that there is also ControlAlignment, but I cannot find any documentation for that option (the Documentation Center links to RandomChoice!?!). What are defined settings for ControlAlignment?
