That is not an expression. It is a special kind of parameter
which can only be used in curly braces with the keys command.
It cannot be used generally in places where an expression is
expected, such as myvar=expression

That should be: string = filemenu("keys\_common.txt")

It uses the same word "filemenu" but in this case it is a proper
expression in parentheses, which is using the built in function filemenu.

See Help, Index, "filemenu" about the difference between using
the built in function: filemenu("filepath")
and the Keys parameter: {filemenu filepath}
