The client you are thinking of is xev, which can be used to display details
about
the keycodes and keysyms that result when you press or release any key on the
keyboard.
Yes, I think the issue here is how the XQuartz server on the Mac converts the
keypress into an X11 Event. XQuartz has a preference that switches the option
keys
between sending Mode_switch and sending Alt_L and Alt_R, but neither of these
is
what is desired here. Instead, as I understand it the ask is for the option
keys to
send Meta_L and Meta_R. The only way I know of to do something like that is to
use
xmodmap on the Mac. Because these are modifier keys you need to change both
the
keysyms and the modifer maps. I think something like this set of xmodmap
commands
would work as a start, though it leaves no keys assigned as mod1 modifiers.
I'm
not sure what the side effects of having no mod1 modifier keys are. It adds
the
two option keys as additional Meta keys and leaves the command keys as
Meta keys as before, and it makes sure that all of the Meta keys are part of
the
mod2 map.
clear mod1
keycode 66 = Meta_L
keycode 69 = Meta_R
add mod2 = Meta_L Meta_R
If you want to check to see that I got the keycode numbers correct, use the xev
program.
If you want to make this sort of change every time you start X11 on your Mac,
you can
save the xmodmap commands in ${HOME}/.Xmodmap and create a
${HOME}/.xinitrc.d/30-xmodmap.sh
file that looks something like this:
$ cat ~/.xinitrc.d/30-xmodmap.sh
[ -r "${HOME}/.Xmodmap" ] && xmodmap "${HOME}/.Xmodmap"
Thanks,
Mike
