Board Thread:Script Suggestions/@comment-33878615-20160713053149/@comment-11733175-20160713231317

As it happens, asking for scripts then being "sarcastic" when the answer is not to your liking is not going to bring about the script. Nor is it likely to make anyone want to help you in the future. At the same time, suggesting the use of system messages as a solution to a personal preference across multiple wikis via the condescending manner of a vague google search (which really wasn't obvious) is unlikely to help the discussion either.

Therefore, I'm closing this in the interests of preventing this getting any more fractious. However, as the script is so trivial, here it is: $(function {    var $input = $('#wpSummary'),        summary = $input.val;    if (summary.indexOf('Undo') === 0) {        $input.val(summary.replace('Undo', 'Undid'));    } });
