The other essential for me is that I have lots of web navigation I do. At present I have a bunch of search shortcuts, @s to go to https://github.com/myorg/%s for example. And for ci and monitoring sites as well. Fast nav. It occurs to me some kind of general macro system that interacts with the clipboard could also work here too.
I did spend a long day playing with clipboard managers that worked with sway and Wayland, and got to a pretty ok spot. But, I put it down and forgot which of the many apps was the one I had finally gotten going! Whoops! Some temptation to roll my own with Deno, maybe.
