Re: Tab and return
"so you have to press the «return» key to return the platen"
What is this thing you call a "return key"[0]? My Royal has a bloody great lever on the left hand side that I have to shove to the right to return the carriage to the first column. It advances the paper a line, too, if I ask it to. Or two lines. Or three or four, depending on the preferences of whoever has control of the Big Red Pencil (and sometimes Blue).
