NX How to add additional options to the horizontal tool bar

 There's no 'Information Object' option on the horizontal toolbar when an object is selected.

Solution

 Right click in an empty area of the ribbon and select "Customize".
 On the Customize dialog select 'Shortcuts' and highlight 'All Objects'.
 

Then go to the 'Commands' tab and search on the item to add to the Horizontal toolbar. Then drag the item to the toolbar.

Now the "Information Object" option is added to the Horizontal tool bar when an object is highlighted.

Additionally you can see the link below to the NX documentation on this topic for more detailed information.
