It is perhaps worth pointing out that in Plan 9 (and in Plan 9 from User Space), Alt is just a key like any other, not a modifier like Shift: you don't have to hold it down through the entire sequence. It is also perhaps worth pointing out that the letter must be a capital X. So you can type Alt, X, 2, 6, 3, a to get ☺. Russ
