Ability to add funciton keys

It would be nice if there was a way to add function keys to apply styles and other atributes. It would also be useful to allow styles to be edited or at least rearrange in the favorites list.

Styles are part of OS X rather than part of Scrivener - they work exactly the same in TextEdit and so forth, so I have no control over them. (You can suggest improvements to the Apple text engine at bugreport.apple.com, though.)

All the best,
