If I understand correctly, you can do what you want with "Constrained Move" (in menu under Tools... Movement):
(The purpose of "Movement Mouse Mode" is different, mainly to allow moving subparts of a model. By default, mouse manipulation moves whole models.)
You can also specify center and axis of rotation if using commands (turn, roll).
I hope this helps,
