There were commands to open web pages using linux commands, in some of yifanlu's launcher menu options. Look there...
Ahh... I see. On the K5, the launcher menu uses lipc commands like this:
lipc-set-prop com.lab126.appmgrd start app://com.lab126.gmail/
It looks like lipc only launches commands defined in a config file. You would need to put URLs you want into whatever file lipc is looking in, and then you could launch them...
