# Roman's Layout There are four layers: - **BASE** is [Norman layout](https://normanlayout.info/). - **SYMB** for numbers and symbols. - **PLVR** is optimized for [Plover](http://www.openstenoproject.org). - **ARRW** for navigation (same fingers for arrows as HJKL on QWERTY). Looking for IJKL arrows? [Here we go](../romanzolotarev-norman-plover-osx/).

Turn off that Bluetooth keyboard. Re-plug you ErgoDox. Enjoy! ## CTRL/ESC Both of those keys are frequently used in Vim. - Tap `CTRL/ESC` to send `ESC`. - Hold `CTRL/ESC` to use as `CTRL`. ## Activate N-rollover - While in **BASE** hold left `SHIFT` and right `SHIRT` and then tap `N`. - Then you can activate **PLVR** and use ErgoDox EZ for steno.
