NX How do you customize "Open in Window" a component in an assembly

If you are in ANT, select a component, ->RM ->you would see "Open in Window", however if you select a component on the screen -> RM -> you would only see "Open in Window" on the horizontal toolbar, but not the vertical toolbar.

How do you customize "Open in Window" in the vertical toolbar?

 1) Menu -->Tools -->Customize

2) Shortcuts

3) Select a Component on the screen.

4) Under Type, Choose Assemblies.Component.

5) Drag "Open in Window" off the horizontal  toolbar.

Here it is after I removed it from the horizontal toolbar.
