This is the bug that most of all makes me long for os9, but apart from this crucial omission, osX is great.


In os9, i pressed ctrl-x etc for emacs C-x, and I pressed (simultaneously) ctrl-alt-x for emacs M-x. Only for some commands you have to press ESC and then the key. In osX, this possibility is blocked. In terminal settings (Keyboard), I can choose to have alt key set as meta key, but that road is blocked, for obvious reasons: Being a linguist, I need the alt key to various non-ascii letters, this was what made me a mac user in the mid eighties. In os9, there was a further option: "alt option as meta". So, how can I get my meta back?

    A very kind person wrote this:

    I found a way to switch which key Mac OS X recognizes as meta. First, uncheck the “Use the system keyboard layout” option in X11 preferences. Then, create the file ~/.Xmodmap and insert the following six lines:

    clear Mod1
    clear Mod2
    keycode 63 = Mode_switch
    keycode 66 = Meta_L
    add Mod1 = Meta_L
    add Mod2 = Mode_switch

    It clears the keymappings for alt and escape and then reassigns them to the reverse of what they were before. Restart X11 and it should pick up the changes.

      I don't think that the question was about anything under X11... It's about Terminal.app, which is not an X11 application.

      I also have been very frustrating by its inability to send the Control+Meta combination. As far as I can tell, there isn't a *single* terminal emulator that runs under OSX capable of sending it. My everyday work requires me to use a console emacs through an ssh connection, so being able to type it is very important. (The alternative is to a highly unergonomic need to press ESC every other keystroke!).

      If anyone figures out a fix, I'd *love* to hear it!

      Thanks,

      Antonio

      [In the meantime, I'll try that X11 trick. It might be the next best thing...]

        You can try pressing "Esc" then Control-anotherkey, it's cumbersome but should work.

        If you look with Google you should find some config examples where are redefine a lot (all?) of terminal keys combinations (and the equivalent binding inside Emacs), but i don't recall if Meta-Control could be flawlessly integrated...

          Hi There,

          You need to configure the mac 'terminal' application so the 'alt / option' key sends 'meta'. In order to do this, go to:

          Terminal > Preferences > Settings > Keyboard

          and select the 'Use option as meta key' checkbox at the bottom of the window.

          I hope that helps,

          -Denali
