Code folding

Code folding lets you temporarily hide sections of code. This can be helpful when working with long code blocks because it lets you focus on specific sections of code you are working on.

To hide code, place your cursor at the far left of a cell. Downward-pointing arrows appear at logical points where you can hide a section of code. Click the arrow to hide a code section. Click the arrow again (now pointing to the right) to show the code.
