Those buttons are called Hotkey’s. HotKeys are most commonly used for sports applications, where instant messages are often used throughout the duration of a game. If you click on the [More...] button, you will see that there is actually a total of 100 programmable HotKey’s.

To program HotKeys, select a key, go to settings and find a file that you want to use. Do this for each HotKey you want to set. Once you have them all loaded onto the key’s, you must [Send Hotkey Files] to store them in the sign controller. After they are stored, you can click any HotKey and [Send] to automatically display that message on your sign.
