Windows 7 includes the ability to add new folders with a keyboard shortcut key combination.
To create a new folder, we normally right-click, select New > Folder. But Windows 7 lets you do it with a keyboard shortcut too.

To do so, simply press Ctrl+Shift+N in an open explorer window & the folder will be automatically created instantly show up, ready to be renamed to something more useful.

For example, click on the desktop and then press Ctrl+Shift+N. You will see that a New folder is created instantaneously all ready to be re-named! You can open in this fashion in any Windows 7 explorer window.
