Tenkeyless
Provided by the ASK Keyboard Dictionary
Describes a small form-factor keyboard that is similar to a full-sized (101 to 105 key) keyboard but omits a dedicated numeric keypad. This is usually done for reducing the overall footprint of the keyboard without sacrificing function or navigation keys, although it has become popular in gaming circles since it allows the user to bring the keyboard and mouse closer together. In specific, "tenkey" refers to the number 0 to 9 keys. The Model M-based 1987 IBM Space Saving Keyboards (SSK) is perhaps the most well known and first popular example of a tenkeyless keyboard.
