The difference between klama and litru seems subtle--is it that klama is focused on origin/destination whereas litru is more about the factthat one journeys?
One specifically requires an origin and destination, the other does not. Most things that litru have an origin and destination as part of the route, and so could also be described with klama, but in such cases using litru means that the origin and destination are not relevant, whereas the route might be (cadzu by itself means that even the route isn't relevant)
And a satellite would be described with litru but a natural satellite like the Moon probably not with klama except in very special circumstances
Seems like cadzu with something meaning "aimlessly" would be good for "go for a walk" :)
That is focusing on the fact that you are moving about on your limbs by human power. You can stretch the meaning of walking to include a wheelchair (a case where the place structure can in fact be used metaphorically, with the wheels serving as "limbs") and thus "go for a walk" without referring to litru. But cadzu does not include what the astronauts are doing on the Space Station when they do a "space walk", whereas the activity might be described as "litru". Thus in Lojban, we map things differently than in English where "space travel" is something more abstract than "space walk".
