  Unless and until desktop OSes make typing symbols not on the keyboard as easy as iOS or Android, I can't be bothered.

    It's pretty easy on Linux with the compose key. To get "≠", you just hit compose, then "/", then "=". That's actually the same number of keystrokes as "!=" (since "!" requires the shift key). For whatever reason, the OS documentation lacks a list of allowed compose key sequences. But they are intuitive enough that you can find many of them through experimentation. For example: Musical sharp ("♯"): compose + "#" + "#". Interrobang ("‽"): compose + "!" + "?". Letter "ñ" as in "jalapeño": compose + "n" + "~". Copyright ("ⓒ"): compose + "(" + c + ")".

      The "compose" key was a new rabbit hole for me. Very handy.

      At least in Debian (Trixie), I have a list in: /usr/share/X11/locale/en_US.UTF-8/Compose

      [Replying to myself...] Oops, I got one wrong. Copyright("©"): compose + "c" + "o". The one I had is bigger: Ⓒ vs. ©.
