Why does the shortcut I created change to NDOF Fit I changed the shortcut for Frame Selected from Number . to Shift F and after I saved the project the shortcut changed to NDOF Fit and I can't change it or remove the shortcut. The only way I can change it is to reset the default settings but that removes everything including my project. 

How do I create a short cut for Frame Selected when it says NDOF Fit.
