If you work with large files, you might want to hide certain pieces of your code. This can be done with code folding . Certain constructs, such as if-statements or classes, can be folded so that they are displayed as a single line in the editor view. You can do this by clicking the little arrow symbols ( and ) next to the statement or declaration. You can Shift+Click an arrow to (un)fold all regions within the given region, e.g., Shift+Click the folding icon of a class to (un)fold all its methods.
