Shift+F for Flipping Normals

[PaoloFurani]

I also discovered that by default Blender has no keymapping for Flip Normals, so I added Shift+F which made it easier. However, I have to either make this change in my default project and also every other .blend file which isn’t based on my default project.

Blender has the Shortcut ( Ctrl-N and Shift-Ctrl-N) for this, read the manual
