Code Folding

Code folding is a feature in text editors and integrated development environments (IDEs) that allows programmers to collapse sections of code (such as functions, classes, or loops) into a single line, hiding the detailed content while retaining a high-level structural overview. For sighted developers, code folding reduces visual clutter and helps navigate large codebases by showing only the code sections currently relevant. For blind developers, code folding could theoretically help by reducing the amount of code that must be traversed linearly via screen reader, but the feature is often inaccessible because the fold/unfold controls rely on visual cues like clickable icons in the editor margin.
