Creation of new folders and renaming with F2

[e-dreyer]

When creating a new folder, it creates a new folder with the default name Untitled Folder. This is very frustrating as I want to immediately give that folder a name. Furthermore, both Windows and Linux have the feature that items can be renamed by pressing F2. I actually use this whenever I want to rename something, rather than right-clicking. It would be great if we had this functionality as well. Thus, when you click on a folder or file, that pressing F2 would enter the rename mode allowing you the rename the item.
