Even on a large ship you wouldn't have anybody on the bridge to do something like switching to auxiliary power. Anything to do with power would be a job for the engineering crew and the Captain would call the Chief Engineer to activate auxiliary power who would then in turn have one of his/her people do the task.That's why I liked the show "The Middle" because Frankie (the mom) will just pour their cereal in a bag and say "No time! Save it for lunch!".
One thing that always bugs me is shows, usually scifi shows where the people are piloting a ship and then the pilot will say something like "Cut in auxiliary power!" and the copilot will have to get up and run way back into the ship to do that. Uh no, that would be at the pilots' controls because that would be something you would need right now, not 30secs later! A pilot would have everything they would need in an emergency right in the cockpit. Now if it was a large ship like a warship, maybe you might have to do that, but not on a shuttle or small ship.
