emacs v.21.2.1 menu bar

[Stephen]

Hello...

I am new to emacs.  When I use emacs through an ssh client (or through a
telnet client) a menu appears at the top of the terminal screen with the
commands File Edit Options Buffers Tools Minibuf Help.

How are these commands accessed?  They look like they are supposed to be
part of a drop down system, but I have never seen that in a terminal window!

Thanks in advance,

Stephen
