1# The default ANSI keymap for DC01 Left

3The keymap looks like a full layout keymap.
4
5This is because the left part of the keyboard acts as the masterm coordinating all four part.
6
7When using the keyboard to connect the other three parts, this keymap overwrites the individual keymaps of the single modules.
8
9When using a module individually, the keymap of that module will take effect.
