# Done! You will now have + and - signs next to your categories. Clicking these allows for easy editing, removing and changing of categories.
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:
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.
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
#save the page.
To change a category, click the "(±)"-Link next to the category name. This will open the [[#Input box|input box]] where you can enter a new category name.
To add a category, click the "(+)"-Link at the end of the category line. This will open the [[#Input box|input box]] where you can enter a new category name.

Clicking the "Cancel"-button would now abort the operation, clicking "OK" would tell HotCat to go on and add the chosen category.
