Featuring only lower case letters, this keyboard is designed for young children who don't yet understand the relationship between capital and lower-case letters. In addition, it features large, color-coded, one-inch keys that are easy to find and press. It is color-coded by key function: vowels are purple, consonants are green, function keys are blue, numbers are red, and punctuation keys are yellow. The keyboard follows a standard layout, without extra macro keys. It will work with a Macintosh although there are no Macintosh-specific keys. See also, the one button Chester Mouse.
