▪ Set the current picker's namespace：

A namespace is a naming prefix for the current picker, changing of namespace enables you to use the picker on different rigs as long as they have similar naming conversions.

1.To set the picker namespace: You simply edit the text shown in the top namespace area. The Ctrl+Alt+Shift+S hotkey in animator mode will just activate the text area.

2.To Grab the namespace from Maya selection: Simply click on the button.

▪Sub-Namespace:

Most types of picker item (Select-button, command-button, attr-Button, slider) may contain a sub-namespace if it is set durning the designing process.

A sub-namespace is an addition to the picker namespace.

Say your picker namespace is set to "myCharacter", and there is a select button has the sub-namespace "bodyRig:chestRig", the select-button contains a member called "chest_ctl", then the final Maya control will turn out to be this:

 myCharacter:bodyRig:chestRig:chest_ctl;

This means when you click this select-button in animator mode, the tool will try to select "myCharacter:bodyRig:chestRig:chest_ctl" in Maya scene.
