gives me my preferred behavior of having arrow keys move the
screen, but if a text line extends beyond the end of one screen
line (i.e., wraps with a \ ) then this macro jumps to the next
text line rather than screen line, making it difficult to reach
the wrapped parts of the line. Is there a way to move single
screen lines relative to wrapped text?
* Wrapping happens at exactly the set character, rather than doing
it at the closest whitespace character (which is easier to read
for writing). Is there a way to wrap at whitespace?
