Thanks jPV for all this informations!

I have just tested and rcmd+c rcmd+v work but rcmd + x dont work in shell (there is no entry in the menu and in available functions in prefs.

@Kronos: It will be fine to have the same hotkeys for clipboard in Ambient and shell.

[EDIT] i have i bizarre thing with Mixer, when i connect an headphones to mini jack and play sound, if i move the balance, the volume down automaticaly... (PowerMac G5)
