Emacs inside Tmux breaks my asterisk? (M-O j is undefined) reddit / emacs ---------------------------------------------------------------------- alfiedotwtf4 ยท 2022-11-03 05:20 \[SOLVED\] I'm not sure what's happening, but when using Emacs inside Tmux, I can't type an asterisk? Instead, the minibuffer says "M-O j is undefined". Anyone know what this actually means? Edit: I'm using uxrvt, but the same happens in xterm. Edit 2: Ok, at least I have a work around - holding shift and it works??! Edit 3: Turns out it was urxvt that was breaking. Switched to Alacritty and everything worked
