The Evil Red Keyboard is an application that allows you to create your own custom keyboard. It has a simple and intuitive interface that allows you to choose from a wide variety of themes and styles. You can also set the layout to the way you want it to be and choose from a variety of languages.

Once you've chosen your keyboard style, you can start adding extra symbols and characters. You can also set the background color to a different color and even use your own images as the background. The keyboard is ready for use and you can start typing and sending messages.

The application also supports the two hand keyboard layout and the landscape orientation. You can set the orientation to either the horizontal or vertical orientation.
