Using XQuartz on MacOS with ksh, this allows me to use Command as Meta. Tested with Emacs and ksh emacs mode.
~/.xmodmap: ! Use command key as meta keycode 63 = Meta_L keycode 71 = Meta_R keycode 66 = Mode_switch keycode 69 = Mode_switch clear mod1 clear mod2 add mod1 = Meta_L Meta_R add mod2 = Mode_switch ~/.Xresources ! Meta characters are converted into a two character sequence ! with the character itself preceded by ESC. xterm*eightBitInput: false On Wed, Feb 5, 2025 at 10:14 PM Nick <atod101...@gmail.com> wrote: > How can I remap these keys so they work as Meta?
