Some time ago I wrote a tip about yanking, and I was informed in a comment that helm has helm-show-kill-ring, which is a replacement for M-y. Turns out that the Ivy suite has counsel-yank-pop, which is a similar thing. Even better, instead of binding M-y to it manually, you can just turn counsel-mode on, and many Emacs commands will be automatically remapped to their counsel equivalents. Nice!
