I use shortcutd and set long-half-press of the camera button to run shell command Code: /usr/bin/osso-xterm "" I find that it loads faster if I specify an empty command with the "" than if I omit that. Alternatively, you can put in an actual command in that instead of make x-term launch executing that command. So /usr/bin/osso-xterm "sudo gainroot" to launch it with root access, etc. I think you may be able to get two x-term windows at once by putting one /usr/bin/osso-xterm command inside the quotes of the other one, actually.
/usr/bin/osso-xterm ""
