[W126 Coupe] question about console buttons

[Gary]

i purchesded my sec about 5 months ago and in our recent move i've misplaced my sec book.  so i need some help with the console buttons.
 
88 sec
 
the 5 buttons that are in a line...i know the ones on each end, one is the defrost and the other is the off and the middle one is the one i use for my heater and a/c.  what are the other two for?
 
also on the upper left there are two buttons...the one with the 3 arrows in a circle what's that for?
 
also below the ashtray there are 3 buttons.  the outside ones are the seat heaters, what's the one in the middle?  looks like a horn.
 
also aren't the doors suppose to lock automatically when you put the car in gear?   how do you lock the doors from the inside.
 
that's all for now.  i'm sure i'll find my book...somewhere in all those boxes.  thanks
