nice, I wonder we could also have some way to scroll
by the column width.. it might be more eye friendly?
would need to try first ;-)

I also tried it with SKIP_COLS_STEP=1, and it wasn't bad

how about having several scroll step options? like:
     , . - SKIP_COLS_STEP=1
     < > - SKIP_COLS_STEP=10
CTRL-< > - SKIP_COLS_STEP=columns width

we could also bind some of this to regular arrows
with SHIFT or CTRL, bacause it's probably the most
convenient binding for this
