# Charybdis (3x5) default keymap > :bulb: Have a look at the [`via` keymap](../via) for a more feature-rich layout. The Charydbis (3x5) default keymap is inspired from the original [Dactyl Manuform](../../../../../handwired/dactyl_manuform) default keymap. This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.
