 - `panel()` : brings up the command palette
 - `show_tags()` : brings up the tag list. From there you can select a tag to search for tagged notes - or yank or insert the tag
 - `rename_note()` : rename the current note and update the links pointing to it
+- `switch_vault()` : switch the vault
 
 To use one of the functions above, just run them with the `:lua ...` command.
