What is code folding?

Code folding is when you can take several lines of code and collapse them. Folding is super useful for situations where code takes up space when you do not need to see it for your current editing. Common cases are things like function definitions, for loops, or large tables.

How does Vim handle folding?

Folding Modes

Vim has several folding modes:

1. manual - you pick where folds go
2. indent - fold by indented blocks
3. syntax - fold by semantic markers in code
4. expr - fold by user expression
5. marker - fold based on Markers that are placed by a user
6. diff - used to fold unchanged text when using Views

For the most part, I'm just going to use manual mode. I know enough of the motions that I can get around easier, and plus since I write in a variety of languages things like indent or syntax might not be sufficient or expressive enough.

Folding Commands

To create a fold, use zf{motion}, where, you guessed it, you can use just about any of the Motions you like.

Folds can also be created using Visual mode. Select the text, then zf.
