How to add two touching toolbar items to NSToolbar

Question

I want to add two touching items, such as a forward and back button, to NSToolbar, like so:

NSToolbar seems to add horizontal margins by default, for each item, like this:

I checked out the XIB source code under the toolbarItem node, and there is no property/attribute that would provide a margin or padding.

Thanks for your help!

If you really want the two items separated (but close together), set the style of the NSSegmentedControl in IB from Rounded to Separated:
