Wikipedia:AntiVandal

AntiVandal is a web-based counter-vandalism tool. It is similar to Huggle in interface and usage, though it is a more lightweight version.

Requirements
Due to the ability of the script to revert edits extremely quickly, it is required to have the rollback right or be included on the script's whitelist. If you do not have the rollback right, you can make a request at the permissions page.

Method 1
Go to Preferences &rarr; Gadgets &rarr; Advanced, check "Install scripts without having to manually edit JavaScript files", and save. Reload this page, and there should be a button which says "install".

Method 2
Add  to your common.js.

Usage
After the script is installed, beside your preferences button, there will now be a link which says "AntiVandal". Clicking this will activate the script.

 * R rolls back the current edit but does not warn the user.
 * Space or ] goes to the next edit.

Menus

 * Warn allows you to select a warning template to give to a user instead of using the default.
 * AIV can add a report for the user at WP:AIV (note that this will report the user who made the currently selected edit, so you must report them before reverting).
