The Multiple Action Tool (MAT) is a semi-automated tool intended to aid extended-confirmed users in reviewing edits and warning users who have engaged in vandalism or edit wars.

To prevent misuse this feature is only available to extended confirmed users. This tool must be used responsibly. Misuse of this tool may result in you either being blocked from using RedWarn, or editing entirely. It is very easy to spam with this tool, so ensure you don't use it too liberally.

There is consensus that the use of the multiple action tool outside of the permitted usage, such as to replace the mass message sender user right, or using the rw.multiAct API outside of the permitted activation methods is a violation of Wikipedia's bot policy. Misuse may result in being blocked from editing.

Revert pending changes or view a page history and select a range of revisions, then click the "Use the Multiple Action Tool between selected revisions" button to activate the tool.

Once loaded, you'll be presented with all the warning levels (standing) and total edit count of each user. To select users, select the filters at the top of the page (i.e <10 edits button, ext.).

You can remove users by clicking the "remove selected" button. An example would be removing experienced editors (i.e. more than 500 edits) by clicking the "Experienced" toggle check button then by clicking remove selected.

You can preview a user's talk page by clicking their account standing icon and view related contributions by clicking the link.

If you see just one user, or just the users you want to add Wikitext to, select all by using the checkbox at the top of the table.

The MAT display can be closed via the "X" in the upper right (which may not be visible without using horizontal scrolling to bring it into view).

Select either "Warn User" or "New Message" from the "set text from" menu, set the content as usual, then click "Apply to selected" to save. Confirm by clicking "Make Changes", then once done, you can close the Multiple Action Tool. Before confirming, please ensure all details are correct.

Clicking any of the filters in the "Toggle Select" menu will toggle the checked state of users who meet the selected criteria (i.e checked -> unchecked / unchecked -> checked).
