As some of you may know, I've started a wonderful journey of sharing Star Trek episodes with my kids (12 and 10 years old). I watched all the original episodes as a kid, but my children continue to come up with questions that I never thought of as a child - so I've been posting questions on this forum and sharing answers with my kids. Here are tonight's questions: (1) Has the question about a bathroom on the bridge ever been answered? (2) After seeing several close ups of Spock and Uhura pushing and manipulating buttons at their respective stations, my son wants to know how they know what buttons to push without any letters, labeling, etc. Did the actors actually have a system/routine that they followed, or did they just random push buttons in the scenes?
