I can recommend http://www.qth.com/inrad/YAE_MENU.htm I have a FT-1000MP Mark-V 
with 250 Hz CW filters.

On my Mark-V I only press the narrow II button an then the filter is working. I 
can also choose the narrow I button which is the 500 Hz filter.

I hope this can help you with some of your questions.
