For higher productivity, AppCode encourages you to use the keyboard for all your tasks.
When you are just getting started with AppCode, try the keyboard hotkeys you already know well. AppCode’s default keyboard layout is designed with your convenience in mind, but you can always choose specific layouts such as those from Xcode or IntelliJ IDEA, or just create your own.
UI customizations would be incomplete without being able to configure the editor itself. AppCode comes with several editor color schemes bundled and makes it possible to create your own custom schemes or modifying existing ones. You can also import your preferred color scheme from Xcode.
If you prefer a dark UI, try the Darcula theme.
Maintain your preferred colors and fonts layout for syntax and error highlighting in the editor, search results, the debugger and consoles via font and color schemes. Use a predefined scheme or create your own (changes are highlighted in the preview immediately so that you can tune it easily).
