Code folding allows you to hide parts of a document in the editor, making
it easier to overview large documents. In Kate the foldable regions are
calculated using rules defined in the syntax highlight definitions and
therefore it is only available in some file formats - typically program source code,
XML markup and similar. Most highlight definition files supporting code folding
also let you manually define foldable regions, typically using the
BEGIN
and END
keywords.
To use the code folding feature, activate the folding markers using -> menu item if they are not already visible. The Folding Markers Pane in the left side of the screen displays a graphical view of the foldable regions, with +/- signs to indicate the possible operation on a given region. A - means that the region is expanded; clicking on the - will collapse the region and a + will be displayed instead.
Four commands are provided to manipulate the state of folding regions, see the menu documentation for details.
If you do not want to use the code folding feature, you can disable it completely using the Show folding markers (if available) option in the Editor Appearance configuration page
