Chicony KB-5591 (semi-ISO)<ref name="F-KB-5591" /> and KB-5592 (ISO) are an AT keyboards from Chicony with an integrated trackball. The trackball replaces the cursor keys, and there are three mouse buttons at the front-left of the case. The single cable splits out to AT and serial connectors for the keyboard and trackball respectively.

There are four lock LEDs on the keyboard: num lock, caps lock, scroll lock, and cursor lock. In cursor lock mode, the trackball transmits cursor keypresses; the toggle for cursor lock is any Ctrl, any Alt, and the right mouse button on the keyboard.<ref>https://geekhack.org/index.php?topic=91811.0</ref>

To guide the user's fingers, the left mouse button has two small bumps on it, and the right button has a small raised bar.

Switches

Chicony are infamous for having routinely changed the switches in their mechanical boards. So far, this board has only been seen with SMK Alps mount switches.
