Built from these letters
CODEX starts with C and ends with X. Sorted, its letters read CDEOX - the shape to hunt for when the grid is scrambled. No letter is used twice, which makes it an isogram. It uses X - among the least common letters in written English.
Same letters, different word
One other word uses exactly these letters. Worth knowing at the board: an anagram fits a grid the same way.
