       | I just tab over to a terminal and use pgrep/pkill for this.

         | Quite annoying, but haven't spent much time debugging it

         | Whether that matters depends on your use. Usually when I want
         | to kill a process it's a program I'm working on and unrelated
         | to emacs itself. This will be very useful for that and I can
         | still always fire up an external terminal to kill things in the
         | rare case where emacs itself is stuck waiting foe something and
         | I can't C-g it. (Actually, since I use emacs EXWM as the window
         | manager, in that situation I would Ctrl-Alt-Fkey to another tty
         | and kill emacs if SIGUSR2 doesn't wake it up - a very rare
         | situation indeed.)

       | If you're on linux, rofi[1] is a very versatile fuzzy-search
       | graphical application. One of the typical ways to use it is to
       | invoke it in script mode (see man rofi-script) with a shell
       | script, where if called without arguments it invokes rofi against
       | that script's stdout, and if called with arguments it runs a
       | different command with that argument. This is nice because I
       | don't have to switch to/open a new terminal or emacs, it's bound
       | to a key I can invoke from anywhere in the graphical session. The
       | kill process script is pretty simple (I filter out the path names
       | from the nix store since I'm using nix)                 if [[ -z
       | "$@" ]]; then           echo -e "\0prompt\x1fKill Process"
       | ps -ax | awk '{$2 = "" ; $3 = ""; $4 = ""; print $0}' | tail -n
       | +2 | sed 's/\/nix\/store\/[^\/]*//'       else           kill $1
