Morse code and interword gaps may be lengthened so the word rate is only 5 words per minute. Using different character and text speeds is, in fact, a common practice, and is used in the Farnsworth method of learning Morse code. Some methods of teaching Morse code use a dichotomic search table. Morse Code cannot be treated as a classical radioteletype (RTTY) signal when it comes to calculating a link margin or a link budget for the simple reason of it possessing variable length dots and dashes as well as variant timing between letters and words.

Braille pattern dots-1245 Braille pattern dots-1245 The Braille pattern dots-1245 ( ) is a 6-dot or 8-dot braille cell with the top four dots raised. It is represented by the Unicode code point U+281b, and in Braille ASCII with G. In unified international braille, the braille pattern dots-1245 is used to represent a voiced velar plosive, i.e. /g/, and is otherwise assigned as needed. It is also used for the number 7. Related to Braille pattern dots-1245 are Braille patterns 12457, 12458, and 124578, which are used in 8-dot braille systems, such as Gardner-Salinas and Luxembourgish Braille. In the Japanese kantenji braille, the
