Looking around on the internet (not being a bidi reader) it seems to
me that it is mostly a programming mistake to let the arrow keys
change direction. (Somehow maybe also from a beginners perspective the
right arrow might mean "go forward".) However for someone editing
texts in some way this is awkward IMO. Here are some links:

(look for "moving the caret").

- http://bugs.dojotoolkit.org/ticket/8037 (just a short complaints
about cursor changing their ways)

- http://www.qsm.co.il/Hebrew/logicUI22.htm - "The logical approach is
sometimes preferred by implementors, mostly because its implementation
is easier. This is not a recommended solution."
