RTL kerning and twisted arrow key direction

Can you tell me, why the direction of the arrow keys is changing in RTL kerning mode?
I am sorry, but this really drives me nuts. It would be much easier for me, if the cursor moves to the right on pressing the right arrow like in LTR mode. Or do I understand anything wrong?

This skewed order does not only affect the positioning of the cursor but also the use of the command and control key for altering the kerning values itself.
