This project is a customizable extension for your keyboard, which will connect to your computer via USB. Your new keypad will be able to send arbitrary strings to your computer with each key press - meaning you can add keys for Slack emoji, shortcuts for your favorite program or game, or even just words or phrases you often use.

Wires are the dark blue lines that electrically connect ports, sheet entries, and pins in your schematic.

Place wires with Place → Wire {{altium-shortcut|p → w}}. Draw a wire from the GND sheet entry to the pin of the GND power port, and another wire from the +3.3V sheet entry to the +3.3V power port. You'll now have something looking like the picture at right.

====Pick Type and Number of Keys====
We're now going to add the actual key switches. We (as of this writing) have two switch types in the library - "white" and "blue." The different colors are for different mechanical properties of the switches; blue switches make an audible "clicking" sound when pressed, and white ones are quieter. You're free to pick either; please just be consistent.
You will also need to pick a number of keys to use. The board template is sized to fit up to 12 - enough to do a traditional number pad. Using fewer keys will save slightly on time, by reducing repetition, but will also limit what you can do with your finished product.
====Place Key Switches====
Bring up the Place Part menu with Place → Part {{altium-shortcut|p → p}}. On the window that comes up, hit "Choose" in the upper right corner. This will bring up the "Browse Libraries" window. From the drop-down at the top, make sure "SSI.IntLib" is selected. All of the parts in the SSI libraries will then be displayed in a large area on the left side of the window. You can search through these parts with the "Mask" field at the top of the window - type in "*" followed by your search term. Try this for a couple of common electronic components, such as "*LED" or "*OPAMP," to see some of the parts in the library.
The keyswitches we'll be using are manufactured by a company called Cherry; you can find them by searching "*CHERRY." Pick either blue or white, and then hit "OK," and then hit "OK" again when the window closes. You will now be dragging a switch symbol on your schematic. Neatly place as many as you would like (up to 12) on the schematic with a bit of space in between them. When you're done, hit {{altium-shortcut|escape}} to stop placing switches, and then hit {{altium-shortcut|escape}} again to exit the place command.
