I want to be able to add a word to the dictionary or to accept it for
the buffer WITHOUT using the middle mouse button and getting a huge list
of meaningless suggestions.
When you are in the middle of Ispell's spell-checking commands, typing
'a' accepts the words and typing 'i' inserts it into your private
dictionary. So if you are at or after a word you want to accept or
insert, type "M-$", which run the command ispell-word, and then press
'a' or 'i', as you see fit. Since flyspell uses the same dictionary,
the change will affect it as well.
Is this what you wanted?
