Thanks a lot.

For anyone else who wants to try this, the complete path to the checkbox is:

       Terminal > Preferences > Settings > Keyboard > Use option as
       meta key

Option is what you want, anyways, because Alt is obtained from pressing Shift+Option, so that's why it didn't show up in your Google searches :)

    I use a mac. To enable the Alt key as meta, do the following:

    In the terminal (your Terminal.app) go:
    Preferences --> Keyboard, and then check the box for "Use option
    as meta key".

        I need to log into a shell on a remote server and then invoke
        Emacs from the command line.  Up until recently my local
        machine was a Windows laptop.  I was running 'putty' locally.
         Putty's front end is a terminal emulator,  and it speaks ssh
        out its back end.

        I recently switched to a Mac, so to accomplish the same task
        I've been running the Mac terminal emulator
        (/Applications/Utilities/Terminal.app) and at the local
        command line I run:

           ssh -p port address@hidden

        After I log into the remote machine's shell, I start up Emacs,
        just as I've been doing for ages.  Almost everything works
        just as it used to, BUT when I need to type a keystroke with
        the Meta modifier (i.e. use the ALT modifier key) the modifier
        isn't recognized.

        Although I can get the same effect by using the ESC key,
        that's often a real pain.  For example, if I want to move
        forward a word at a time, I'll usually type ALT+f, and then
        release the "f" key and type it again several times without
        ever releasing the ALT key.  To do the same thing with the ESC
        key, I've got to press ESC, release ESC, press F, release F,
        repeat until the cursor's where I want it.

        Clearly putty sends something in the SSH protocol that lets
        the remote Emacs know when the ALT key is pressed.  I don't
        know if it's the Mac terminal emulator or the Mac
        implementation of SSH that's failing to pass that information
        along.

        Does anyone here have any idea what I need to do to allow the
        information about the state of the ALT modifier key to be
        passed to the server where Emacs is running?
