in moriji, when you say "i'm just walking!" you can just say "i walk", maybe with an annoyed tone. if you want to be a real ass, you can throw in "ditanem" because using it with the past tense verb what you are essentially saying is "i walked, and i will do it again!"
so yeah by itself this is a pretty shitty particle so i grouped it in with "just" and "only" because it pretty much means the same thing in terms of adding emphasis in a sort of dramatic way (because i don't want to add stress accent).
savus is used at the end of a sentence similar to desu except only in the case you say you are going to do something, i call it perfect reflexive future tense, whether or not this is actually a correct term i don't really know, i also don't really care, i'm going to go take a nap
