'''Chicony KB-5591''' (semi-ISO)<ref name="F-KB-5591" /> and '''KB-5592''' (ISO) are an [[AT keyboard interface|AT]] keyboards from Chicony with an integrated [[trackball]]. The trackball replaces the [[cursor keys]], and there are three [[mouse button]]s 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 switch]]es.
