I'm now trying Calva. Is there a corresponding feature with cider-scratch? https://docs.cider.mx/cider/usage/misc_features.html#using-a-scratchpad
The equivalent would be to create a New Untitled Text File and set the language to Clojure. On Mac, the default keyboard shortcut sequence is cmd+n cmd+k m and start type Clojure.
There are also Fiddle files, but those are actual files: https://calva.io/fiddle-files/
Great, thanks!
