I’m currently using Klipper, and it’s fine, I suppose, but I miss the ability to cycle through the previous clips with simple keypresses, like in the emacs killring (the only thing I miss from my very brief experimentation with emacs back in the day).
PS: actually with Klipper I can go back and forth in the clipboard history too. I don’t know if this is possible in Emacs. For example, if I go back two history steps, and then realize that I went too far by one step, I’d type
H-v H-v H-C-v C-v. TheH-C-vis “undoing” the lastH-v.
