Some methods of teaching Morse code use a [[dichotomic search]] table.
[[File:Morse code tree3.png|thumb|center|upright=3.5|International Morse code [[binary search]] tree: The graph branches left for each ''dit'' and right for each ''dah'' until the character representation is reached. Official [[International Telecommunication Union|ITU]] codes are shown as black letters on dark grey, and are complete, including punctuation; a few non-ITU extensions are shown in grey letters on light grey, but many others are left out. ITU [[Prosigns for Morse code|prosigns]] are circled in red with red text and are complete; unofficial prosigns are orange and are mostly complete.]]
