Psh::Builtins::Cd(3)

•   "cd DIR"

    Change the working directory to DIR or home if DIR is not specified. The special DIR "-" is interpreted as "return to the previous directory".

    "cd %num" will jump to a certain directory in the stack (See also builtin "dirs").

    "cd +num" and "cd -num" will go forward/backward in the directory stack.
