Playful Code Adventures
Regions allow you to name a section of your code to better organize it. You can also collapse or condense regions by using the - and + signs next to the region area. If you hover over a collapsed region, it will show the code inside.
CTRL + K and then CTRL + D will format your code. This is helpful, for example, if you have code that isn't indented. Using these two keyboard shortcuts will have Visual Studio reformat your code.
Commenting multiple lines is easy with keyboard shortcuts. Multiple lines can be commented and uncommented by selecting them and clicking the comment icon, or by using the keyboard shortcut [CTRL + E, C] to comment, and [CTRL + E, U] to uncomment. (Microsoft Visual Studio Ultimate 2012 Screenshots)
