Input assistance
The editor uses a monospaced font, four-space indentation, and no automatic wrapping. Enter preserves indentation and adds four spaces after a code line ending in a colon. Brackets and quotes are paired automatically and can surround selected text. Folding supports functions, classes, conditions, loops, exception blocks, and other indented blocks.
