I assume in friction mode that would be possible. and I also remember reading about an extra "ghost" click. here is a link to a pic:
They are 6 speed. There is also an additional position that may or may not be a usable cog position. 6 and 7 speed cog spacing was also different. There is a friction mode that allows use with any speed. Don't try and represent them as anything else. If I wanted a 7 or 8 speed index shifter,that is what i'd buy.
