The Hooleon Corporation has been making custom keyboard products since 1982. Originally two people working out of their garage, the company now is a multi-million dollar, internationally-known corporation offering a large selection of keyboards and accessories for customizing your keyboard.
Among these products are replacement keys in large print, customizable labels to apply to your existing keys, and keyboard typing helps- color coded labels that indicate which finger should be used to strike the keys. They also manufacture braille keyboards, language keyboards (in several languages), and Dvorak keyboards- which have a different arrangement of letters than the traditional "QWERTY" keyboard.
They make many other products, including "novelty keys" such as a red "panic" button or an "any" key that will add some fun to your keyboard. They also will make keys to your specifications if their regular line doesn't have what you need.
