You cannot use defined variables as patterns (this is a common mistake).
Variables appearing in a pattern are always bound to (parts) of the
matched value. Something close to what you want would be :

try
let put c = putch c; Queue.add c buffer in
match char_code with
| ch when ch = Key.kEnter -> put '\n'
| ch when ch = Key.kBksp -> put '\b'
| ch -> put (Key.to_char ch)
with Key.Not_printable -> ()
