How do I create a fold from a visual selection?

Explanation

In visual mode, pressing zf creates a manual fold from the selected lines. This lets you collapse sections of code or text.

How it works

• Select lines with V and motions
• Press zf to create a fold
• The selected lines are collapsed into one line
• zo opens the fold, zc closes it

Example

Select a function body with Vip, press zf to fold it. The fold shows something like:

+-- 15 lines: function process() {----

Tips

• :set foldmethod=manual must be set for this to work
• zd deletes a fold (unfolds it permanently)
• zf{motion} creates a fold without visual mode
• zR opens all folds, zM closes all folds
• za toggles the fold under the cursor
