Inexpensive latching switches were ordered for the prototyping area. These keys were meant to be programmed as the arrow keys, HOME, END, PAGE UP, and PAGE DOWN. For instances where a lot of scrolling is necessary, like infinite scrolling web pages, these would be useful. There are some games and programs where scrolling like this would be useful.

Arranged and soldered latching switches

The buttons were soldered to the prototyping area by their common center pins to keep them in place. All the common pins were connected to ground. White wire was used to connect the normally open contacts of the switches to the exposed pads made for this kind of experimentation.

Soldering for latching switches

A single layer was programmed for the keys to use the arrows, home/end, and paging buttons. Not much attention was given to the way the wires were connected, so the keys were arranged in software and they all worked. There was some repair soldering necessary on the IO expander before the keys worked.
