Hmm, I wonder if having , e n in Spacemacs would be a good addition (assuming I didn't add it already). It seems a more logical way to think about that action, whereas buffer is more generic and implementation specific to Emacs.
@lee if you see calva commands for those key bindings, let me know. You should be able to do SPC SPC
and type calva paredit or something like that. If I spot anything, I'll let you know.
Looks like you might have, on spacemacs, , e n
brings up a submenu for namespace loading
• a - reload-all
• l - ns-reload
• n - eval-ns-form
• r - ns-refresh
