It's more about replacing typed text than using shortcuts, but there's espanso.

This may sound convoluted, but you could create a custom command in Keyboard->Shortcuts (Add New -> Command or Script) that uses ydotool (uses a service) that is basically ydotool type "|>" and then create a shortcut of Ctrl+$ for it.

Edit: I just tried this, it seems like custom shortcuts aren't working?

Sorry, may need to submit a bug report.

After exploring all solutions, and fighting a few things to build either Hawck or Espanso on openSUSE (I'm not a dev), I finally managed to find instructions to get Espanso to build (it's all there, fellow desperate random reader of the future). Since you can define the keyboard layout AND the variant of said keyboard you are using with Espanso, it's working as expected.

So now, I've associated ":$" with "|>", not sure how well that'll work in the future, but it's far easier to type on my keyboard at least... Also, I gained a tool to insert greek symbols and smileys everywhere that I didn't know I needed, but very quickly adopting! 😅

Thanks all for your help!

You could use a clipboard tool to copy something to the clipboard and then paste it in one command. There is such a common tool for Wayland: https://github.com/YaLTeR/wl-clipboard-rs . It's at least in the official repository in Archlinux. The command could be something like this:

wl-copy "|>" ; wl-paste

Off course you would lose the current clipboard content this way. But I guess a script could easily be written to backup and restore clipboard, but not entirely sure how safe it is.
