Firstly the Move Type command default is move Namespace which I don;t think I have ever used ... but I use Move to Another File virtually non-stop.
Also the R#4 version of Move Type now has a dropdown that is stopping me tabbing properly - so I used to do Move Type, Default was Namespace, but Tab-Tab-DownArrow-Enter moved it to another file
Now it is Tab-Tab-Tab-Down-Enter ... anooying to have yet another keypress, making it 6 off the top of my head ... Move to Another FIle, Move to Another Namespace on the main R# keypress would be a massive performance boost
