Mechanical Keyboard DIP Switches

I’ve owned a WASD keyboard for a while but totally forgot about the DIP switches on the bottom. What’s a DIP switch? From Wikipedia:

A DIP switch is a manual electric switch that is packaged with others in a group in a standard dual in-line package (DIP). The term may refer to each individual switch, or to the unit as a whole. This type of switch is designed to be used on a printed circuit board along with other electronic components and is commonly used to customize the behavior of an electronic device for specific situations.

On a WASD V2 87-key, these switches let you enable Mac mode (switch command and option), swap caps lock with CTRL, activate function commands, and more. These can be set in the OS or via different applications, but setting them at the hardware level is very convenient.
