it does still not work.
the fuction is defined as such:
function show_command(URL) {
open_window().location.href='http://texshow.contextgarden.net/cmd/' + URL;
}
and thus redirects to some url under http://texshow.contextgarden.net/.
but no matter what that url is, the subdomain always redirects to the url http://wiki.contextgarden.net/Category:Reference/en (no, not http://wiki.contextgarden.net/Category:Reference/en/TheCommandName!)
please fix it, whoeveer runs texshow.contextgarden.net
