Yet on the 65 what you get when you press 'f-1' 'int' is not exactly intuitive.

Craig, I agree, the F-1 functions may not be considered intuitive, unless you understand that they represent the inverse or complement of the F function associated with the key. But I personally prefer the method that HP chose on the 65, it makes for a cleaner keyboard with fewer labels and it assumes a somewhat higher level of mathematical sophistication on the part of the user.

We had a discussion of this point back in 2011:
