Is there a way to assign multiple key equivalents to a Menu Item in Cocoa (via IB or programmatically)?

Question

Specifically, I want my "New" menu item to respond to both Cmd+N and Cmd+T since it will open a new document in a tab.* How can I do this either in Interface Builder or programmatically?

* I can explain the reasoning further if needed, but I'm hoping to avoid a discussion of the merits and rather focus on how to do it, not why to do it.

Answer 1

Make a second one (easiest way being to duplicate it) and set it as hidden. It won't show up when the user pulls open the menu, but as long as it's enabled, its key equivalents should still be in effect.
