It is about the cursor position before you start typing (you want it at
the location where the text would be appear). When you focus-in an empty
text field in a LTR-language the cursor is at the left side, in a
RTL-language on the right side.

Usually it can be just deduced from the language but I remember the case
of entering phone numbers, which were also LTR-numbers in RTL-languages.

It does contain a cursor position (see cursor_position and
preedit_cursor events).
