(The following text is taken from Wikipedia) "The quick brown fox jumps over the lazy dog" is an English-language pangram - a sentence that contains all the letters of the alphabet. The phrase is commonly used for touching-typing practice, testing typewriters and computer keyboards, displaying examples of fonts, and other applications ivolving text where the use of all letters in the alphabet is desired. (It is thus a fitting selection for filler text.)
