CudaText Usage Tips
Maximize your CudaText productivity by mastering the command palette (Ctrl+Shift+P) for quick access to all editor functions without navigating complex menus. Utilize the tab splitting features to create customized workspace layouts tailored to your specific projects—consider using 2- or 3-pane layouts for reference code, documentation, and active editing. Take advantage of the multiple carets and selections feature for simultaneous editing of multiple code sections, significantly accelerating repetitive modifications. Configure lexer-specific settings through the JSON configuration files to optimize syntax highlighting and behavior for your primary programming languages. Explore the Python plugin ecosystem to extend functionality—essential additions include CudaLint for code linting, CudaFormatter for code formatting, and the external tools plugin for integrating compilers and other development utilities. Use the portable version on USB drives for a consistent editing environment across multiple computers. For large file handling, leverage the binary/hex viewer mode to examine massive log files and data files without loading them into standard editing mode.
