Hold on. It does segfaults, but this is not me, this is the isRTL
function implemented in Cursor.cpp. It's fails when it tries to ask a
LyxText from the CursorSlice it occurs in.
Can someone help me fix this function?
How can I get to the head of the paragraph (or some place not in an
inset) that the inset my cursor is currently pointing at, is found?
Any references?

So it does not segfault aymore?

No space please: if (cur.isRTL())

Hum... using goto is not recommended practice. Couldn't you just use our
"standard" dispatch method instead?

                if (cur.isRTL())
                        cur.dispatch(FuncRequest(LFUN_CHAR_BACKWARD));

Maybe you'll need an additional flag to indicate that RTL should not be
checked in LFUN_CHAR_BACKWARD.

Anyway, this is only style issues. More importantly, Dov, Mostafa, could
you please confirm that what Elazar is proposing is the right thing to do?
I seem to remember that some Arabic countries read math LTR and others
RTL so maybe we need some kind of preference settings. Personally I'd be
in favour of a cursor that follows the logical screen oriented arrows,
be it for text or for math. But I am not just a novice; you guys should
do some research for the perfect solution. If there is no such perfect
solution we should allow the user to fine tune this via preference settings.

Abdel.
