I'm not sure I'm following, sorry.  Can you show a screenshot, and
explain what did you mean by "move with the text as it should"?

Also, what text did you insert?  If my reading of the defmacro and its
call is correct, you just put a single button alone on its line, in
which case it should behave like a single character, and should be
displayed at the right edge of the window when paragraph direction is
right-to-left.
