Even if you don't use VS Code/Clojure specifically, the "Action" names should be the same or similar with other Paredit extensions, so you can become familiar.
Best advise I have for learning Paredit is doing the same as you would if you were to learn Vim: Every time you think "How can I do X faster?" look up the way to do it and write it down on a cheatsheet. After a couple of times it'll become muscle memory.
