Now I found it, I was looking for "_" instead of "underscore" word,
now I got it. Thanks.
A simple way to find out which variables need a variable definition
is to byte-compile the source file. *Note Byte Compilation::. If a
non-special variable is used outside of a ‘let’ form, the byte-compiler
will warn about reference or assignment to a free variable. If a
non-special variable is bound but not used within a ‘let’ form, the
byte-compiler will warn about an unused lexical variable. The
byte-compiler will also issue a warning if you use a special variable as
a function argument.
(To silence byte-compiler warnings about unused variables, just use a
variable name that start with an underscore. The byte-compiler
interprets this as an indication that this is a variable known not to be
used.)
