A TKL (TenKeyLess) keyboard is a compact keyboard layout that removes the dedicated numeric keypad (the "tenkey" section) found on a standard full-size keyboard, while retaining nearly all other keys. Here’s a breakdown:

Design & Size:

TKL keyboards are roughly 80% the size of a full keyboard. By eliminating the numpad, they save significant desk space and reduce keyboard width by 5-7 inches. This allows for a more ergonomic setup, bringing the mouse closer to the body and reducing shoulder strain.

Key Retention:

Despite the missing numpad, TKL keyboards keep the function row (F1-F12), main alphanumeric section, arrow keys, and the essential navigation cluster (Insert, Delete, Home, End, Page Up, Page Down). The modifier keys (Ctrl, Alt, Win, Shift) and the top number row remain intact.

Use Cases & Benefits:

TKL is popular among gamers (freeing up mouse space), minimalists, users with smaller desks, and those who prioritize ergonomics or portability. Typists who rarely use a numpad find it efficient. The layout maintains full functionality for most tasks, except for heavy numeric data entry.

Trade-offs:

The obvious sacrifice is the numpad. Users who need to enter numbers frequently (such as accountants and data analysts) may find TKL less efficient, although external numpads are an option.
