Tenkeyless

Tenkeyless (TKL) refers to a computer keyboard layout that omits the dedicated numeric keypad located to the right of the main alphanumeric area. By removing the 17-key numpad, a typical tenkeyless keyboard has about 87 keys, compared with 104 on a full-size board. The term is commonly applied to keyboards around 80% in size, though not every 80% keyboard is labeled TKL. Variants exist; smaller compact forms such as 75%, 65%, and 60% remove more keys but are not generally described as tenkeyless; they are related but distinct categories. Most TKL keyboards retain the standard alphanumeric block, the function (F) row, the navigation cluster (arrow keys, Home/End, Page Up/Down) and modifiers, though some models place some keys in layers.

Benefits: The reduced footprint frees desk space, allows a closer mouse position, and often improves ergonomics for users with smaller desks or who prefer a two-handed mouse setup. They are typically lighter and easier to transport, appealing to gamers and professionals seeking portability.

Drawbacks: The absence of a numeric keypad can hinder numeric data entry and certain workflows; users may rely on on-screen keyboards, software overlays, or programmable layers to access keypad functions. Some users may need time to relearn key placements.

History: The concept emerged with PC keyboard designs through the 1980s and 1990s and became common among enthusiasts in the 2000s; tenkeyless, often abbreviated TKL, is the standard label used in retail and discussion.
