Left/Right are for positioning the cursor.  They have nothing to do with
the order people read the text in.  I don't want my mouse to change
direction on RL text.

Huh?  I suggest visual order.  Period.

I have no idea what you are imagining here.

Press left, end up at the next position to the left.  Press right, end
up at the next position to the right.  No need to even recognize whether
the glyphs at question are R2L or L2R: the effect is immediately
obvious.  Without thinking, without even knowing anything about the
R2L/L2R properties of the glyphs.  forward-character and
backward-character require more thinking.
