In VS2010 I had a shortcut set up Alt+Up/Down to move lines of code up or down, just like I used to have in Eclipse in my Java days.
Now since Powe
If you have Resharper, then you can hit Ctrl + Shift + Alt + ↑ to move the current line up. or Ctrl + Shift + Alt + ↓ to move one line down.
This works in VS 2012 Premium with Visual Studio keyboard scheme in Resharper 7 (7.0.97.60 to be precise).
Edit: This is mapped to 'ReSharper.ReSharper_MoveUp'/'MoveDown' commands.
