i don't know which Gem you are using, but here (linux) [gemkeyname]
works fine with uppercase, lowercase and special characters (e.g.
Ctrl-x): each gets a separate identifier, according to its name.


as far as my testing went, [gemkeyname] worked fine on linux and w23
(though the naming of special keys like "Left" might be differing across
 platform (but this might as well be fixed already)), and though i have
not done any testing on os-x, i believe that a lot of other people have...

it would be interesting to know what system you are on (and whether it
allows you to use upper/lowercase characters anyhow - afair the zx80
does not have lowercase characters; please tell us that you managed to
run pd/Gem on it)

if this is really a bug, please file a bug-report at

i have once posted a patch to add a "kiosk" mode to pd which disables
all the menus and keyboard-shortcuts in pd.
you should still be able to find it in the sourceforge patch-tracker (of
pd that is: http://sf.net/projects/pure-data)
(it won't get accepted into main pd though, as there are other better as
in: more granular) ways to acchieve this)

otoh, if you are doing an installation with Gem you will most likely
want to run it in fullscreen mode, so that people do not see the
underlying pd and OS.
in this case [keyname]/[key] won't help you, since they only work when
they have the keyboard focus (which they don't when the gemwindow is
before them).

a good way to get the keyboard regardless of the the window-focus is
[hid] (and probably [hidin])


oh, and don't forget to remove the  Control, Alt, Meta keys from your
keybaord, as people will likely keep rebooting your machine....
