The Alt key on my US English keyboard going to OS X X11.app going to qemu-0.8.2 (using my own qemu-0.8.2 RHEL 4 package) on my RHEL 4 Linux box is not happening. Instead, this is spewed to the console.

Warning: no scancode found for keysym 310

Strange, since xev sees the keypress just fine:

KeyPress event, serial 24, synthetic NO, window 0x1000001,
    root 0x57, subw 0x0, time 411185488, (11,-16), root:(31,48),
    state 0x0, keycode 66 (keysym 0xffe7, Meta_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

I don’t know why the keysym reported by qemu doesn’t match the keysym reported by xev. I’m guessing that it has something to do with the fact that qemu uses SDL, which probably has its own keymap routines, that are apart from the X11 routines.
