Completing read supports hash tables, once representation candidate has been selected one can then use the key to get value of some quite different or very complex data structure. (setq h (make-hash-table :test 'equal)) (puthash "United States" [("ABC" 30 t)] h) (puthash "Australia" 2 h) (puthash "United Kingdom" 3 h) (message "%s" (gethash (completing-read "Choice: " h) h)) ⇒ "[(ABC 30 t)]" -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns Sign an open letter in support of Richard M.
