What does error "No modules containing clojure.main" during REPL configuration mean?

I see, I needed to download Clojure into the project.

How do I switch between editor and REPL windows using a keyboard shortcut? Cmd-\ and Esc

Cursive newbie here... Seems like IntelliJ is barfing on one of my deps -- claiming it can't "index it"?

how do I make IntelliJ feel better and/or restart /redo the indexing?

tried restarting it...

Invalidate the cache

Filemenu

There’s an option in the File menu to “Invalidate caches and restart”

lol, I’m too slow a typist

ah ok thx!
