# Michael Guterl's Ortho 4x12 Layout
I use this layout for both my Planck and Levinson. I also have a very similar
[keymap](/keyboards/preonic/keymaps/mguterl) for my Preonic.
Check out my [userspace](/users/mguterl) for the custom keycodes that are used
in keymap.c.
At a very high level I use 4 layers:
* Qwerty - Letters
* Util - Vimkeys for navigation and other convenient things
* Raise - Numbers and F keys
* Lower - Symbols
```sh
make planck/rev5:mguterl:flash # For Planck rev5 or earlier and Planck Light
make planck/rev6:mguterl:flash # For Planck rev6
make keebio/levinson/rev2:mguterl:dfu # For Levinson rev2
```
