40 * SECTION:ctkshortcutssection
41 * @Title: CtkShortcutsSection
42 * @Short_description: Represents an application mode in a CtkShortcutsWindow
43 *
44 * A CtkShortcutsSection collects all the keyboard shortcuts and gestures
45 * for a major application mode. If your application needs multiple sections,
46 * you should give each section a unique #CtkShortcutsSection:section-name and
47 * a #CtkShortcutsSection:title that can be shown in the section selector of
48 * the CtkShortcutsWindow.
49 *
50 * The #CtkShortcutsSection:max-height property can be used to influence how
51 * the groups in the section are distributed over pages and columns.
52 *
53 * This widget is only meant to be used with #CtkShortcutsWindow.
