How do I activate all of the HUD buttons around my navball?

The only buttons that actually work are the SAS, Prograde, and Retrograde. Do I unlock these as I progress in career? Or am I missing something?

In a career game, they show up based on the "piloting level" of your ship.

With a level 1 pilot, you get the retrograde/prograde buttons.

With a level 2 pilot, you get normal, antinormal, radial in, radial out.

With a level 3 pilot, you get target / anti-target and hold maneuver.

...The same deal applies to probe cores, too-- higher-level probe cores act like higher-level pilots.  For example, OKTO acts like a level-0 pilot, HECS like a level-1, OKTO2 like a level-2, and the 1.25m-and-bigger cores like a level-3.

Oh! Well that makes sense. Thanks!
