52. ShowRaceMenu, ShowBirthsignMenu, and ShowClassMenu
All three of these work in a similar way. The first will pull up the menu that lets you change your race and facial features, the second will let you change your birth sign, and the third will let you change your major attributes and skills. These things are touchy, though, so you need to follow these instructions on using them. First, type in the command but do not close the console window. Make the desired changes to your character, with the window open, then hit Esc and make a new save - load this new save. You can now close the console window, if it's still open, but at no time before now should you close it or it will revert all of your character's stats in that menu to their default.
Ex.: N/A
Links: N/A
Other applications: N/A
Notes: None.

Hope that helps...
