Finally downloaded Rocket for Mac. It’s a free utility that allows you to invoke an emoji picker just buy typing a colon (:) and the name of the emoji you’re looking for.

It’s very cool and works nicely. I don’t know that I need it; Launchbar effectively does this, and there is a keyboard shortcut for pulling up the emoji picker in macOS. I do both of those a lot. I’m going to leave Rocket running and see if it sticks.
