Well, what I was hoping for is to select a component from the component browser to place into the model, then as it is moving with the mouse at the insertion point, rotate it, so that it's in the correct orientation. Kind of a building block assembly system. And, sometimes a component would need to be rotated, sometimes not.
Obviously, I can put the component "down", rotate, then move it, but was just hoping to simplify that process in the creation of numerous modular assemblies.
But it seems that the component being placed is not actually selected, per se, so no shortcut key works on it.
