From Debuntu

Folding is a feature of Vim that allows to hide a block of text under a fold. This is pretty usefull when dealing with lengthly code files as it gave a better overview of the code by hiding bit of code that are not really meaningful at a specific time.

Creating/Deleting Folds

Creating

Visual Mode

In visual mode, select the bit of text you want to fold and type:

zf

Motion Mode

In Motion Mode, you can create a fold like this:

zf5j

This will create a fold from the current line to 5 line below.

Escape Mode

In Escape Mode, folds can be created like that:

:.,+3fo

Will fold from the current line until 3 lines below. The syntax is:

{range}fo[ld]

zd

To delete all folds:

zE

Some more tips

Closing from the current { to the matching }. Make sure your cursor is on the opening curly bracket and run:

Folding from cursor to matching_string:

zf/matching_string
