Yeah, I was quite afraid of the length of my email :) Thanks for reading

Well, in this case my goal is to let the user see the content of
not-full rows without explicitly looking for it, and to move rapidly
from an item to another without too much corrections.

Good catch. Also speaking from a Western perspective, I find it somewhat
confusing to be brought at the opposite side of the one I was moving to
(and columns can be long and involve scrolling, while rows don't
scroll). My point is that currently left/right let you navigate through
all the items, while up/down keys can leave a row "hidden".

I don't know the original goals of that features: currently it seems to
me that if you use modifiers than nothing happens.

I'm less sure of this, now. If a wrap around for up/down is desired, the
current behavior of always passing through the "none" item probably
makes more sense. Unless we find a dedicated key to select that item,
which could solve the situation. Any idea?

Wow. Too many things I didn't consider!
Honestly, my plans were to simplify code and provide a more consistent
behavior than the current one, that I find somehow confusing.
I guess we should wait for some hints on the desired up/down behavior
and then see how to proceed (if there's need to).
Thanks for your thoughts!
