 ### Behavior
 
 Press tab for completions appropriate to the current input.
-`mde <...> <prior word> <current word>`
+`mde <...> <prior word> <current word><TAB>`
 
 Completions are calculated based on the current word and the prior word. 
 1. If the current word starts with `-`, present matching options, eg `--version` for the current word `--v`.
 2. Else, if the current word is empty and the prior word is an option that takes an argument, present the type of the argument, eg `.BOOL.` for the option `--user-must-approve`.
 3. Else, if the current word is the type of argument, from the rule above, present the default value for the option. e.g. `1` for the type `.BOOL.` for the option `--user-must-approve`.
