Help:Gadget-HotCat
HotCat is a JavaScript extension of the MediaWiki user interface. It augments the category bar with quick links to remove, change, or add categories. It can be activated in the "Gadgets" tab of Special:Preferences.
How to use
Whenever a page is loaded, HotCat looks for the category bar. If there are visible categories, it adds links to easily remove, change or add categories. The new links are:
- "(−)" after a category: when clicked, the category is automatically removed.
- "(±)" after a category: when clicked, an input field to change this category is opened.
- "(+)" at the end of the list of categories: when clicked, an input field to add a category is opened.
- "(++)" at the front: when clicked, enters multi-change mode, allowing modifying more than one category.
If HotCat can detect that a certain category is not in the page text itself but was transcluded onto the page from a template or other transclusion, it will not add these links. Only categories that are present in the wikitext of the page itself can be modified through HotCat.
Removing a single category
To remove a category, simply click the "(−)" link next to the category name. If the page does indeed contain this category, HotCat will remove it automatically. It will
- open a new window or tab in your browser with the current page opened for editing,
- hide the whole edit form, so that you cannot edit,
- edit the page to remove the category, and
- save the page.
Changing a category
To change a category, click the "(±)" link next to the category name. This will open the input box where you can enter a new category name.
Adding a category
To add a category, click the "(+)" link at the end of the category line. This will open the input box where you can enter a new category name.+
