Now this would be a rather handy solution, if my laptop had some more expendable key to re-purpose as a compose ey. The right alt keys closeness to the arrow cluster, makes it a very handy way to "Go back" in history using any program that behaves like a web browser. And I couldn't live without using my menu key to quickly access spelling corrections in pidgin >_>.

However if I could make xmodmap or something else to bind meta+menu into acting as a compose key, that would work.quite nicely.
