Since you've already fixed this, I'm just nitpicking. The relevant
details here are not the keycodes but the keysyms. Your keyboard
generates, in hardware, a number corresponding to each key (= physical
piece of plastic) on the board; this number is the keycode. The X
server receives this and maps it into a keysym. The server sends the
keysym to the application with input focus; apps should never see raw
keycodes. (On PC hardware, anyway; not sure about how other systems
work off the top of my head.)
For this situation, you'd want to see the keys generating keysyms Meta_L
and Meta_R.
