| It sounds to me like what you're trying to do is beyond the scope of both bindings and the target/action paradigm.
You want to engage in a lengthy operation triggered by "leaving a text field by tab."
Because there is no binding for "extied by tab" in the NSTextField class, there is nothing to bind against.
Because there is no "send action on exited by tab" option in NSTextField, no action will be sent.
I would think about whether your design is appropriate, considering two popular paradigms for responding to user interface changes are unsuitable for your needs.
Maybe it would be better to have a single button outside of the text fields that was responsible for "stimulating the next calculation." Then you could hookup whatever keyboard equivalent you wanted to the button instead of taking advantage of the fact that tabbing out of a text field *sometimes* means "I just changed a value."

Okay, the normal target/action deal will work.
But I'm curious: Is what I've described beyond the scope of Cocoa bindings?
