Editing Key Tronic KB 5153 (section)

==Description==
The right hand side of the keyboard contains a large trackpad, a little short of six units square. This trackpad can be used both for macro/hotkey input and as a pointing device. Ready-made and custom templates can be fitted to the trackpad to allow it to be used as a large grid of hotkeys. The trackpad is advertised as "programmable" but it's not made clear whether the programming is handled in software, hardware or both.

This keyboard is AT / XT switchable, via a single jumper header located on the back of the unit. The trackpad has a dedicated on/off key, while the function keys only run up to F10. The keyboard also has an internal speaker, which emits a small chirp upon normal keystrokes. 

Internally, the trackpad circuit board is marked as "ELOGRAPHICS INC, E232(3.6 x 3.6)"
