In Eclipse, selecting a line and pressing Alt + ↑/↓ will move the line up and down, a quick way to avoid copy&paste. Is there an equivalent in Visual Studio?
In Visual Studio 2013 and later, this functionality is built in. ALT + UP/DOWN will move a line up or down.
If you need this functionality in VS2012 (works with VS2010 too), take a look at the MoveLine Visual Studio Extension or the Productivity Power Tools suite.
ReSharper's Ctrl + Shift + Alt + ↑/↓/←/→ is even more powerful - when on the beginning of the line, it will move the entire line, but can also be used to move entire methods, change the order of parameters, etc.
This is now working out of the box with Visual Studio 2013, same way as in Eclipse.
In Visual Studio 2013 and later, you can move lines up and down using Alt + ↑ / Alt + ↓. Unfortunately this will not adjust the indentation if you move between blocks, as of today only ReSharper (and all other IDE's by Jetbrains including Rider) can help you with that.
To move entire blocks of code around you can move the cursor to its head and press Ctrl + m twice fast to collapse it, and then use the command above to move it around.
Here is a neat reference to all default keyboard shortcuts in different versions of Visual Studio.
With the VSCommands extension, you have exactly that keyboard shortcut. And, by the way, a Stack OVerflow notification toolbar :)
