Alt key not working in Emacs SSHing X11

Question

Hello this isn't a coding question but...
I ssh through my mac using X11, and I am using emacs. I am trying to use the "ALT" key for combination but it seems to not be working. I have tried using the "option" key, and "FN + option" both seems to not work.

I had the same problem before. The hint on http://hints.macworld.com/article.php?story=20040425231058862 helps me.

To summarize, you should use xmodmap to remap alt / option in X11.

Put the following in your ~/.Xmodmap file:

clear Mod1
keycode 66 = Meta_L
add Mod1 = Meta_L
