Ctrl-Shift-S = Save As

[Snow]

The fact that someone is asking here for a shortcut proofs that not all user prefer to do every single task by clicking a button or selecting a menu item.

I don't know which version of Blender you're referring, but even the oldest version on my computer (v2.49) let's you move the object along axis by simply grabbing the colored arrow and drag the object to the desired position.

Back to the shortcuts in AC3D. The few shortcuts available do only work, if the mouse cursor is at the right position. If you left the cursor in one of the value fields of the Replicator, or the Extrude pane or Create 2D Text or something similar, and closed that window, the shortcuts don't work any longer because you're still typing into this fields without seeing it.
Even basic tasks like switching the modes don't work via shortcut if you forgot the cursor in a value field. That means you always have to check whether the mouse cursor is within one of the view windows AND you didn't forget the text cursor somewhere.

That is not intuitive at all. It's simply annoying.
